I am new to Docker and not so good in Linux commands. I have followed following commands to install Docker in Ubuntu-14.04.
Using this guide,
apt-get update
apt-get -y install docker.io
ln -sf /usr/bin/docker.io /usr/local/bin/docker
sed -i '$acomplete -F _docker docker' /etc/bash_completion.d/docker.io # it does not work
# sed: can't read /etc/bash_completion.d/docker.io: No such file or directory
So using reference, I have used,
sed -i '$acomplete -F _docker docker' /etc/bash_completion.d/docker
update-rc.d docker defaults
docker version provide following,
Client version: 1.6.2
Client API version: 1.18
Go version (client): go1.2.1
Git commit (client): 7c8fca2
OS/Arch (client): linux/amd64
Server version: 1.6.2
Server API version: 1.18
Go version (server): go1.2.1
Git commit (server): 7c8fca2
OS/Arch (server): linux/amd64
And tried with images like hello-world & busybox successfully. But I failed with commands like,
docker system prune
# docker: 'system' is not a docker command. See 'docker --help'.
docker network
# docker: 'network' is not a docker command. See 'docker --help'.
Have I missed steps in installation part or did I misunderstand anything?
You have used official ubuntu way of doing it.
apt-get install docker.io
These packages would be outdated. Try using official docker way.
Set up Docker Registry,
apt-get update
apt-get install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
Install Docker CE,
apt-get update
apt-get install docker-ce
Verify the installation,
docker run hello-world

I'm remotely connecting to a school server (Ubuntu 20.04.2 LTS) through Visual Studio Code (VScode, version 1.66) to perform some tasks, and today I follow docker.com (https://docs.docker.com/engine/install/ubuntu/) to install docker engine on Ubuntu.
when I do sudo docker run hello-world to verify that Docker Engine is installed correctly by running the hello-world image after all steps, it shows error like this:
docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.
See 'docker run --help'.
After that I check the docker version, it shows
Client: Docker Engine - Community
Version: 20.10.14
API version: 1.41
Go version: go1.16.15

Then look at sudo docker info, which shows

errors pretty printing info
After I unstall and reinstall docker follow this tutorial, it still shows such an error, I think I need to follow the server side of docker, but I don't know how to do it?

You should first start and enable docker in systemctl
systemctl start docker
systemctl enable docker
Just solved a similar issue with this
The first thing you should do is to have Docker Desktop installed on your pc, of which you can get here https://docs.docker.com/desktop/windows/wsl/
You should also enable wsl2,
Just going through the documentation from the link above should be enough.
Make sure you go into Settings>Resources>WSL Integration and enable Ubuntu-20.04 or any other distro you are using.
Also make sure Settings>General>Use the WSL 2 based engine... box is checked
Since yesterday (without a change on config fails) I started to get error:
Cannot connect to the Docker daemon
Here is the snippet of the error:

I am using Debian on the worker. Even with pure Docker setup (without any other config) docker daemon is not reachable.

Thanks in advance!
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 -
this 4 lines are one single command. copy paste it.
sudo apt-key fingerprint 0EBFCD88
pub 4096R/0EBFCD88 2017-02-22
Key fingerprint = 9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88
uid Docker Release (CE deb) <docker#docker.com>
sub 4096R/F273FCD8 2017-02-22
set up the stable repository. You always need the stable repository,
sudo add-apt-repository \
"deb [arch=amd64] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) \
stable"
Update the apt package index one more time.
sudo apt-get update
Install the latest version of Docker CE
sudo apt-get install docker-ce
test if it is installed
docker --version
INSTALL DOCKER COMPOSE
Run this command to download the current stable release of Docker Compose:
sudo curl -L "https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
Apply executable permissions to the binary:
sudo chmod +x /usr/local/bin/docker-compose
test it
docker-compose --version
I am doing the steps as shown below to install docker:
sudo apt-get update
sudo apt-get install docker
The to start docker I am using sudo service docker start.But then it says docker : unrecognized service. I have followed every steps , is there any step missing in this process
Please remove all old packages by using this command.
sudo apt-get remove docker*
I think you have to install repo by using following command.
if you use 64bit Ubuntu version
$ sudo add-apt-repository \
"deb [arch=amd64] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) \
stable"
and after that
sudo apt-get update
sudo apt-get -y install docker.io
And confirm version by using
dom#dom-pc:~/web$ docker version
Client:
Version: 1.12.6
API version: 1.24
Go version: go1.7.4
Git commit: XXXXXXX
Built: Tue Mar 14 09:47:15 2017

Cannot connect to the Docker daemon. Is the docker daemon running on this host?
and if you wanted to upgrade to a later version
ls /usr/bin | grep docker remove these files
docker
docker-containerd
docker-containerd-ctr
docker-containerd-shim
dockerd
docker-init
docker-proxy
docker-runc
wget
https://download.docker.com/linux/static/stable/x86_64/docker-17.06.1-ce.tgz
(or whatever stable version you wanted)
tar xfvz docker-17.06.1-ce.tgz
cp docker/* /usr/bin/
docker -v and you're done.
Follow these steps
$ sudo apt-get remove docker docker-engine docker.io
$ sudo apt-get update
$ sudo apt-get install docker-ce
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

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
