Ubuntu 16.10 : get recent docker & docker compose version? - docker

I'm looking to use Docker compose with v2 docker-compose.yml syntax.
When I'm following the documentation (https://store.docker.com/editions/community/docker-ce-server-ubuntu?tab=description) old docker and docker-compose version has installed :
$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
$ sudo add-apt-repository \
"deb [arch=amd64] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) \
stable"
$ sudo apt-get update
$ sudo apt install docker docker-compose
.../...
$ dpkg -l |grep docker
ii docker 1.5-1 amd64 System tray for KDE3/GNOME2 docklet applications
rc docker-ce 17.03.1~ce-0~ubuntu-yakkety amd64 Docker: the open-source application container engine
ii docker-compose 1.5.2-1 all Punctual, lightweight development environments using Docker
ii docker.io 1.12.6-0ubuntu1~16.10.1 amd64 Linux container runtime
ii python-docker 1.8.0-0ubuntu1 all Python wrapper to access docker.io's control socket
ii python-dockerpty 0.4.1-1 all Pseudo-tty handler for docker Python client (Python 2.x)
In order to use version 2 docker compose file format I need more recent version.
Documentation page of Docker Compose : https://github.com/docker/docker.github.io/blob/master/compose/compose-file/compose-versioning.md
Version 2 files are supported by Compose 1.6.0+ and require a Docker
Engine of version 1.10.0+.
How do I get recent version of docker engine & docker compose ?
I googled this many times today without fine any "simple" solution.
My system : Ubuntu 16.10
Thanks for your help,
David

The easiest way to install Docker is to run:
curl -sSL https://get.docker.com/ | sh
You will probably need to run apt-get remove docker docker-compose first.
To install docker-compose, I normally grab the latest release from the docker-compose Github project e.g:
curl -L https://github.com/docker/compose/releases/download/1.12.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

Is it possible to nest docker/podman containers

I run Fedora 35, and need to run an app in docker in ubuntu.
I was able to get and run ubuntu via podman
podman pull ubuntu:20.04
and setup do docker there, but can't make it run as I probably didn't enter podman properly probably. I used:
podman run -it ubuntu:20.04
where I ran:
su -
apt update; apt upgrade
apt install inetutils-ping nano sudo npm
apt install apt-transport-https ca-certificates curl gnupg
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \ $(lsb_release -cs) stable" |sudo tee /etc/apt/sources.list.d/docker.list > /dev/null apt update
apt install docker-ce docker-ce-cli containerd.io
to start docker via systectl is not possible in the container, and dockerd command gives many error, mostly that it can't access overlay, and probably network (iptables)
ERRO[2022-05-07T23:14:18.803335993+02:00] failed to mount overlay: operation not permitted storage-driver=overlay2
ERRO[2022-05-07T23:14:18.803397023+02:00] exec: "fuse-overlayfs": executable file not found in $PATH storage-driver=fuse-overlayfs
ERRO[2022-05-07T23:14:18.803500924+02:00] AUFS wdas not found in /proc/filesystems storage-driver=aufs
ERRO[2022-05-07T23:14:18.803887884+02:00] failed to mount overlay: operation not permitted storage-driver=overlay
Is it possible at all to run and app with service to have open port to outside of docker, and podman as there are 2 layers of nested containers?
It is not possible to use the default storage driver of type overlay inside another container, you need to change the storage to vfs. Maybe https://docs.docker.com/storage/storagedriver/vfs-driver/ helps.
Disclaimer: This works definitely in case of running podman in docker, but the other way around I have not tested.

Installing docker-compose v2.1.1 in Ubuntu [duplicate]

I have installed docker-compose using the command
sudo apt install docker-compose
It installed docker-compose version 1.8.0 and build unknown
I need the latest version of docker-compose or at least a version of 1.9.0
Can anyone please let me know what approach I should take to upgrade it or uninstall and re-install the latest version.
I have checked the docker website and can see that they are recommending this to install the latest version'
sudo curl -L https://github.com/docker/compose/releases/download/1.21.0/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose
But before that, I have to uninstall the present version, which can be done using the command
sudo rm /usr/local/bin/docker-compose
but this can be used only when the installation was done using curl. I am not sure if the installation was done by curl as I have used
sudo apt install docker-compose
Please let me know what should I do now to uninstall and re-install the docker-compose.
First, remove the old version:
If installed via apt-get
sudo apt-get remove docker-compose
If installed via curl
sudo rm /usr/local/bin/docker-compose
If installed via pip
pip uninstall docker-compose
Then find the newest version on the release page at GitHub or by curling the API and extracting the version from the response using grep or jq (thanks to dragon788, frbl, and Saber Hayati for these improvements):
# curl + grep
VERSION=$(curl --silent https://api.github.com/repos/docker/compose/releases/latest | grep -Po '"tag_name": "\K.*\d')
# curl + jq
VERSION=$(curl --silent https://api.github.com/repos/docker/compose/releases/latest | jq .name -r)
Finally, download to your favorite $PATH-accessible location and set permissions:
DESTINATION=/usr/local/bin/docker-compose
sudo curl -L https://github.com/docker/compose/releases/download/${VERSION}/docker-compose-$(uname -s)-$(uname -m) -o $DESTINATION
sudo chmod 755 $DESTINATION
The easiest way to have a permanent and sustainable solution for the Docker Compose installation and the way to upgrade it, is to just use the package manager pip with:
pip install docker-compose
I was searching for a good solution for the ugly "how to upgrade to the latest version number"-problem, which appeared after you´ve read the official docs - and just found it occasionally - just have a look at the docker-compose pip package - it should reflect (mostly) the current number of the latest released Docker Compose version.
A package manager is always the best solution if it comes to managing software installations! So you just abstract from handling the versions on your own.
If you tried sudo apt-get remove docker-compose and get E: Unable to locate package docker-compose, try this method :
This command must return a result, in order to check it is installed here :
ls -l /usr/local/bin/docker-compose
Remove the old version :
sudo rm -rf docker-compose
Download the last version (check official repo : docker/compose/releases) :
sudo curl -L "https://github.com/docker/compose/releases/download/1.24.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
(replace 1.24.0 if needed)
Finally, apply executable permissions to the binary:
sudo chmod +x /usr/local/bin/docker-compose
Check version :
docker-compose -v
If the above methods aren't working for you, then refer to this answer: https://stackoverflow.com/a/40554985
curl -L "https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-$(uname -m)" > ./docker-compose
sudo mv ./docker-compose /usr/bin/docker-compose
sudo chmod +x /usr/bin/docker-compose
Based on #eric-johnson's answer, I'm currently using this in a script:
#!/bin/bash
compose_version=$(curl https://api.github.com/repos/docker/compose/releases/latest | jq .name -r)
output='/usr/local/bin/docker-compose'
curl -L https://github.com/docker/compose/releases/download/$compose_version/docker-compose-$(uname -s)-$(uname -m) -o $output
chmod +x $output
echo $(docker-compose --version)
it grabs the latest version from the GitHub api.
Here is another oneliner to install the latest version of docker-compose using curl and sed.
curl -L "https://github.com/docker/compose/releases/download/`curl -fsSLI -o /dev/null -w %{url_effective} https://github.com/docker/compose/releases/latest | sed 's#.*tag/##g' && echo`/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose && chmod +x /usr/local/bin/docker-compose
Do it in three steps. (showing for apt-get installs)
Uninstall the last one. e.g. for apt-get installs
sudo apt-get remove docker-compose
Install the new one (https://docs.docker.com/compose/install/)
sudo curl -L "https://github.com/docker/compose/releases/download/1.29.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
and then
sudo chmod +x /usr/local/bin/docker-compose
Check your version
docker-compose --version
Simple Solution to update docker-compose
This will remove the existing binary of docker-compose and install a new version.
sudo cd /usr/local/bin && sudo rm -rf docker-compose
sudo sudo curl -SL https://github.com/docker/compose/releases/download/v2.2.3/docker-compose-linux-x86_64 -o /usr/local/bin/docker-compose
sudo chmod +x docker-compose
for the latest version visit https://github.com/docker/compose/releases and replace the latest one with v2.1.1
I was trying to install docker-compose on "Ubuntu 16.04.5 LTS" but after installing it like this:
sudo curl -L "https://github.com/docker/compose/releases/download/1.26.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
I was getting:
-bash: /usr/local/bin/docker-compose: Permission denied
and while I was using it with sudo I was getting:
sudo: docker-compose: command not found
So here's the steps that I took and solved my problem:
sudo curl -L "https://github.com/docker/compose/releases/download/1.26.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo ln -sf /usr/local/bin/docker-compose /usr/bin/docker-compose
sudo chmod +x /usr/bin/docker-compose
use this from command line: sudo curl -L "https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
Write down the latest release version
Apply executable permissions to the binary:
sudo chmod +x /usr/local/bin/docker-compose
Then test version:
$ docker-compose --version
If you installed with pip, to upgrade you can just use:
pip install --upgrade docker-compose
or as Mariyo states with pip3 explicitly:
pip3 install --upgrade docker-compose
Using latest flag in url will redirect you to the latest release of the repo
As OS name is lower case in github's filename, you should convert uname -s to lower case using sed -e 's/\(.*\)/\L\1/'.
sudo curl -L "https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s|sed -e 's/\(.*\)/\L\1/')-$(uname -m)" -o /usr/local/bin/docker-compose && sudo chmod +x /usr/local/bin/docker-compose
On mac (also working on ubuntu):
sudo curl -L "https://github.com/docker/compose/releases/download/<release-version>/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
NOTE: write the as here:
https://github.com/docker/compose/releases
Use,
$ sudo curl -L "https://github.com/docker/compose/releases/download/1.24.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose && sudo chmod +x /usr/local/bin/docker-compose
$ docker-compose -v
Docker Engine and Docker Compose Plugin
Since Microsoft took over Docker they worked on porting docker-compose to their Docker Engine CLI plugins. For future support and updates I would recommend using docker compose plugin (Notice the missing dash) which can be install via the docker-compose-plugin package. The following instructions assume that you are using Ubuntu as Distro or any Distro thats using apt as package manager.
Installation Preparations
Update your mirrors:
sudo apt-get update
Make sure the following packages are installed:
sudo apt-get install \
ca-certificates \
curl \
gnupg \
lsb-release
After that add the official Docker GPG Key:
sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
And finally add the the stable repository:
echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
Also make sure Docker Engine and other needed dependencies are installed:
sudo apt-get install docker-ce docker-ce-cli containerd.io
Installation of docker compose plugin
sudo apt-get install docker-compose-plugin
Any future updates of the plugin are easily applied via apt.
For further reference take a look at the official installation instructions of Docker Engine and Docker Compose.
After a lot of looking at ways to perform this I ended up using jq, and hopefully I can expand it to handle other repos beyond Docker-Compose without too much work.
# If you have jq installed this will automatically find the latest release binary for your architecture and download it
curl --silent "https://api.github.com/repos/docker/compose/releases/latest" | jq --arg PLATFORM_ARCH "$(echo `uname -s`-`uname -m`)" -r '.assets[] | select(.name | endswith($PLATFORM_ARCH)).browser_download_url' | xargs sudo curl -L -o /usr/local/bin/docker-compose --url
On ubuntu desktop 18.04.2, I have the 'local' removed from the path when using the curl command to install the package and it works for me. See above answer by Kshitij.
In my case, using Windows + WSL2 with Ubuntu 20.04, was necessary only this:
sudo apt update
and then:
sudo apt upgrade
Centos/RHEL
Follow my answer below if you're using Centos7 with an x86-64 architecture. This answer is also available in my github.
Stop Your Docker Containers
I noticed other answers did not talk about stopping your docker containers/images instances before attempting to upgrade gracefully. Assumptions are inevitable but can be costly. Onward we go!
Options to update Docker-Compose
There are 2 options to upgrade docker-compose if you first downloaded and installed docker-compose using the Curl command.
Using Curl, jq package, and Github's direct URL to the docker-compose repository.
Using Curl, Sed, and Github's direct URL to the docker-compose repository.
Note: some of the commands below require "sudo" privileges.
Demonstration
The script below was saved to a file called "update_docker_compose.sh". You need to give this file executable permissions.
Like so:
chmod +x update_docker_compose.sh
"docker_docker_compose.sh" file content:
#!/bin/bash
# author: fullarray (stackoverflow user)
# Contribution shared on: stackoverflow.com
# Contribution also available on: github.com
# date: 06112022
# Stop current docker container running
docker stop containerID
# Remove current docker network running
docker rm containerID
# Remove image of target application(s)
docker image rm imageID
# Delete either dangling (unatagged images) docker containers or images or network
docker system prune -f
# This step depends on the jq package.
# Uncomment jq package installation command below if using Centos7 x86-64.
# sudo yum install jq
# Declare variable to get latest version of docker-compose from github repository
compose_version=$(curl https://api.github.com/repos/docker/compose/releases/latest | jq .name -r)
# Declare variable to target installation directory
target_install_dir='/usr/local/bin/docker-compose'
# Get OS and build (assumes Linux Centos7 and x86_64)
get_local_os_build=$(uname -s)-$(uname -m)
# Execute curl command to carry download and installation operation
curl -L https://github.com/docker/compose/releases/download/$compose_version/docker-compose-$get_local_os_build -o $target_install_dir
# Use chmod to modify permissions to target installation directory (to make it executable)
chmod +x $target_install_dir
# Print docker-compose version to terminal to verify upgrade
$(docker-compose --version)
Edit the script with variables specific to your environment
The script above has a few variables you need to edit with values specific to your docker environment. For instance, you need to replace container ID and image ID with the values that the following commands output.
docker ps
and
docker images output
Once you finalize creating the file (including the edits). Switch to the directory that contains the file. For example, if you created the file in /home/username/script/update_docker_compose.sh
cd /home/username/script
Last, run the script by executing the following
./update_docker_compose.sh
Option 2
Create a script file name "update_docker_compose.sh"
Edit the file and add the following content:
#!/bin/bash
# author: fullarray (stackoverflow user)
# Contribution shared on: stackoverflow.com
# Contribution also available on: github.com
# date: 06112022
# Stop current docker container running
docker stop containerID
# Remove current docker network running
docker rm containerID
# Remove image of target application(s)
docker image rm imageID
# Delete either dangling (unatagged images) docker containers or images or network
docker system prune -f
# Declare variable to target installation directory
target_install_dir='/usr/local/bin/docker-compose'
# Get OS and build (assumes Linux Centos7 and x86_64)
get_local_os_build=$(uname -s)-$(uname -m)
# Execute curl and sed command to carry out download and installation operation
# compose_latest_version=$(curl -L "https://github.com/docker/compose/releases/download/`curl -fsSLI -o /dev/null -w %{url_effective} https://github.com/docker/compose/releases/latest | sed 's#.*tag/##g' && echo`/docker-compose-$get_local_os_build") -o $target_install_dir
# Use chmod to modify permissions to target installation directory (to make it executable)
chmod +x $target_install_dir
# Print docker-compose version to terminal to verify upgrade
$(docker-compose --version)
Edit the script with variables specific to your environment
The script above also has a few variables you need to edit with values specific to your docker environment. For instance, you need to replace container ID and image ID with the values that the following commands output.
docker ps
and
docker images output
Once you finalize creating the file (including the edits). Switch to the directory that contains the file. For example, if you created the file in /home/username/script/update_docker_compose.sh
cd /home/username/script
Last, run the script by executing the following
./update_docker_compose.sh
This is the method of installing docker compose version 2.12.x
Update debian package manager
# apt-get update
# apt-get install docker-compose-plugin
Then install the plugin manualy
DOCKER_CONFIG=${DOCKER_CONFIG:-$HOME/.docker}
mkdir -p $DOCKER_CONFIG/cli-plugins
curl -SL https://github.com/docker/compose/releases/download/v2.12.2/docker-compose-linux-x86_64 -o $DOCKER_CONFIG/cli-plugins/docker-compose
Give permisson of execution of file
chmod +x $DOCKER_CONFIG/cli-plugins/docker-compose
Last test the installation
docker compose version
// Docker Composer Version v2.12.2
If you have homebrew you can also install via brew
$ brew install docker-compose
This is a good way to install on a Mac OS system
Most of these solutions are outdated or make you install old version.
To install the latest
sudo apt install jq
DOCKER_COMPOSE_VERSION=$(curl --silent https://api.github.com/repos/docker/compose/releases/latest | jq .name -r)
sudo curl -L "https://github.com/docker/compose/releases/download/$DOCKER_COMPOSE_VERSION/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
Well, my case was pretty weird. I am using wsl2, and Docker Desktop (Windows 11). I stop getting this error after rename the folder "docker" to "config-dev-server" and update de Dockerfile like this this:
COPY ./docker/apache/apache2.conf /etc/apache2/apache2.conf
to
COPY ./config-dev-server/apache/apache2.conf /etc/apache2/apache2.conf
With a newer Docker Desktop for Mac 3.3.0, you don't need to install Docker Compose as a seperate package. Docker Compose comes as a first class citizen installed with Docker by default. Check out the below CLI:
docker compose version
Docker Compose version 2.0.0-beta.1%

WSL ubuntu docker installation error. with `unix:///var/run/docker.sock.` message

I installed docker with the following command:
sudo apt update
sudo apt install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable"
sudo apt update
sudo apt install docker-ce
But when I run docker ps, I get the following error:
XXXXX#DESKTOP-XXXXX:~$ docker ps
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
You cannot run Docker on WSL directly (you don't have the same kernel capabilities that you have with Linux distros).
You can run Docker in HyperV and configure you Docker client in WSL to connect to it: https://nickjanetakis.com/blog/setting-up-docker-for-windows-and-wsl-to-work-flawlessly
Or start experimenting with WSL 2 Docker backend (it's not that mature, probably has a lot more limitations and bugs): https://docs.docker.com/docker-for-windows/wsl-tech-preview/
You should start the docker service, for Debian distro you can run the command:
sudo service docker start
or run the docked command

nvidia-docker : Unknown runtime specified nvidia

I tried to install the nvidia-docker after installing docker-ce. I followed this : https://github.com/NVIDIA/nvidia-docker to install nvidia-docker. It seems to have installed correctly.
I tried to run:
$ sudo docker run --runtime=nvidia --rm nvidia/cuda nvidia-smi
docker: Error response from daemon: Unknown runtime specified nvidia.
See 'docker run --help'.
Although, this works (without --runtime=nvidia):
$ docker container run -ti ubuntu bash
Some additional info on my system: It is an ubuntu server 16.04 with 8 GPUs (Titan Xp) and nvidia driver version 387.26. I can run nvidia-smi -l 1 on the host system and it works as expected.

}
I have come across: https://github.com/NVIDIA/nvidia-docker/issues/501, but I am not sure how I should go about it.
From nvidia-docker github repo:
curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | sudo apt-key add -
distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.list | sudo tee /etc/apt/sources.list.d/nvidia-docker.list
sudo apt-get update
sudo apt-get install -y nvidia-docker2
sudo pkill -SIGHUP dockerd
Actually, you can try to restart docker daemon by following command.
sudo systemctl daemon-reload
sudo systemctl restart docker
Or you can try to reboot your system.
to make nvidia-docker work
This is how I resolve the above problem for CentOS 7; hopefully it can help anyone who has similar problems.
Add necessary repos to get nvidia-container-runtime:
distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
curl -s -L https://nvidia.github.io/nvidia-container-runtime/$distribution/nvidia-container-runtime.repo | sudo tee /etc/yum.repos.d/nvidia-container-runtime.repo
(Optional) In my case, I disabled the experimental repos:
sudo yum-config-manager --disable libnvidia-container-experimental
sudo yum-config-manager --disable nvidia-container-runtime-experimental
Install nvidia-container-runtime package:
sudo yum install nvidia-container-runtime
Update docker daemon:
sudo vim /etc/docker/daemon.json
with the path to nvidia-container-runtime:
{
"runtimes": {
"nvidia": {
"path": "/usr/bin/nvidia-container-runtime",
"runtimeArgs": []
}
}
}
Finally, you need to make docker update the path:
sudo pkill -SIGHUP dockerd
It seems you may need to purge docker and reinstall it as in the post:
github issues
sudo apt remove docker-ce
sudo apt autoremove
sudo apt-get install docker-ce=5:18.09.0~3-0~ubuntu-bionic
sudo apt install nvidia-docker2
From nvidia-docker Frequently Asked Questions:
Why do I get the error Unknown runtime specified nvidia?
Make sure the runtime was registered to dockerd. You also need to reload the configuration of the Docker daemon.
Change the --runtime=nvidia tag to --runtine=gpus all hopefully it will run

Cannot install docker machine in ubuntu running in virtual box

I am trying to set up whole docker eco system in ubuntu linux running in virtualbox. I succeed in installing docker engine. But I cannot install docker compose and docker machine. Below are the steps I followed to install docker machine.
$ base=https://github.com/docker/machine/releases/download/v0.14.0 &&
curl -L $base/docker-machine-$(uname -s)-$(uname -m) >/tmp/docker- machine &&
sudo install /tmp/docker-machine /usr/local/bin/docker-machine
I am getting below error
/usr/local/bin/docker-machine: line 1: Not: command not found
While running the command docker-machine --version
first uninstall older versions first
sudo apt-get remove docker docker-engine docker.io
Update the apt package index:
$ sudo apt-get update
Add Docker’s official GPG key:
$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
