I building docker image. But it does not success.
/Users/username/.vim exists on my host os, But it does not success.
How I can success docker- build?
Error Message:
Step 16 : ADD /Users/username/.vim/ /root/.vim
lstat Users/username/.vim/: no such file or directory
The following is my Dockerfile.
Dockerfile:
FROM ubuntu:latest

RUN mkdir ~/pyworks

You cannot execute ADD (or COPY) on a file that is not inside the directory that contains your Dockerfile.
The reason for that is that building docker images is meant to be a deterministic build. If I build the Dockerimage on my computer with your Dockerfile, I would have a different .vim
The docker team impose this limitation to encourage people using a self contained directory with a Dockerfile, and any file to add to it.
In your case, you will need to copy the file in the same directory of the Dockerfile first, and run:
ADD .vim /root/.vim
Or arguably better:
COPY .vim /root/.vim
Use this form instead. It works with hidden files(dot files) and filename contains whitespaces.
ADD ["/Users/username/.vim/", "/root/.vim"]
https://docs.docker.com/engine/reference/builder/#/add
Please remove tailing slash after .vim
So, it will go as
ADD /Users/username/.vim /root/.vim

I am trying to install tesseract-ocr to docker from a Dockerfile. When I build the Dockerfile everything looks normal and i get no errors but when I run the container tesseract is not installed.
If I access the container using sudo docker exec -t -i <container_id> /bin/bash and manually install tesseract using apt-get install -y tesseract-ocr-all it installs and works perfectly. Why doesn't it work when I try to install it during the build process?
My Dockerfile looks like this:
FROM ubuntu:20.04
ARG DEBIAN_FRONTEND=noninteractive
RUN apt-get update \
&& apt-get install -y tesseract-ocr-all
RUN tesseract --version
FROM python:3.7
WORKDIR ocr
COPY requirements.txt .
RUN pip3 install --no-cache-dir -r requirements.txt
COPY . .
Thanks!
It looks like you are leveraging Docker multi-stage builds without realizing it.
When you put FROM python:3.7, you essentially throw away everything you have done above that, since you start a new stage.
The easiest solution I can see is to move
RUN apt-get update \
&& apt-get install -y tesseract-ocr-all
RUN tesseract --version
into the FROM python:3.7 stage, and remove the FROM ubuntu:20.04 stage.
You need to switch your user, since you likely don't have permission to run those commands. Something like this should work:
USER root
RUN apt-get update \
&& apt-get install -y tesseract-ocr-all
USER <switch back to previous user>
You'll need to figure out what the default user is to switch back, which you can probably find in the Ubuntu docs or using whoami.
Created a Docker file in oreder to install Tomcat server from Unix as bashe os
My Dockerfile:
FROM ubuntu
RUN apt-get update && apt-get upgrade -y #to update os
RUN apt-get dist-upgrade
RUN apt-get install build-essential
RUN apt-get install openjdk-8-jdk # to install java 8
RUN apt-get wget -y #to install wget package
RUN apt-get wget https://mirrors.estointernet.in/apache/tomcat/tomcat-9/v9.0.37/bin/apache-tomcat-9.0.37.tar.gz #to download tomcat
RUN tar -xvzf apache-tomcat-9.0.37 # unzipping the tomcat
RUN mkdir tomcat # craeting tomacat directory
RUN cp apache-tomcat-9.0.37/* tomcat # copying tomact files to tomact directory
Command to create Docker Image from Docker file:
docker build -t [img name] -f [file name] .
On execution, while installing java package am getting like this:
'''After this operation, 242 MB of additional disk space will be used.
Do you want to continue? [Y/n] Y'''
You are getting the prompt because the command is awaiting user input for whether or not to install a package. The -y flag you're using for a few of them (like wget) allows bash to assume a yes. Add this flag to all your installation commands.
By the way, there's quite a few potential issues with the Dockerfile you posted.
For example, you have RUN apt-get wget ...
Are you sure that is what you want to do, and not just RUN wget ...? Unless wget is a command that apt-get takes, which it isn't, it will cause unexpected behavior.
You also seem to be missing the command to start the Tomcat server, which can make it so that nothing happens when you attempt to run the image.
I think you should add DEBIAN_FRONTEND=noninteractive when running the apt-get commands, something like this:
RUN apt-get update && \
DEBIAN_FRONTEND=noninteractive apt-get install build-essential -y
Also, it's considered bad practice to use multiple RUN steps which could be consolidated into one. More about Dockerfile best practices can be found here.
I am trying to create a docker image with my go application. The application (which was developed on MacOS) depends on confluent-kafka-go which in turn depends on librdkafka-dev which I install in the Docker image like so:
FROM golang:1.1
RUN apt-get update
RUN apt-get -y install librdkafka-dev
VOLUME /workspace
WORKDIR /workspace/src/my/app/folder
ENTRYPOINT ["/bin/sh", "-c"]
I am getting the following error:
my/app/folder/vendor/github.com/confluentinc/confluent-kafka-go/kafka
../folder/vendor/github.com/confluentinc/confluent-kafka-go/kafka/00version.go:44:2: error: #error "confluent-kafka-go requires librdkafka v0.11.5 or later. Install the latest version of librdkafka from the Confluent repositories, see http://docs.confluent.io/current/installation.html"
As far as I understand the latest version is installed.
How can I fix it?
I had a similar issue a few weeks ago. IIRC confluent-kafka-go requires a recent version of librdkafka-dev, which simply was not yet released to alpine or others.
I was able to find it for ubuntu though, so my solution (which was more involved than I hoped for, but it worked), was to start from clean ubuntu, install librdkafka-dev, install Go version that I want and compile inside docker.
Here's how it looks:
FROM ubuntu
# Install the C lib for kafka
RUN apt-get update
RUN apt-get install -y --no-install-recommends apt-utils wget gnupg software-properties-common
RUN apt-get install -y apt-transport-https ca-certificates
RUN wget -qO - https://packages.confluent.io/deb/5.1/archive.key | apt-key add -
RUN add-apt-repository "deb [arch=amd64] https://packages.confluent.io/deb/5.1 stable main"
RUN apt-get update
RUN apt-get install -y librdkafka-dev
# Install Go
RUN add-apt-repository ppa:longsleep/golang-backports
RUN apt-get update
RUN apt-get install -y golang-1.11-go
# build the library
WORKDIR /go/src/gitlab.appsflyer.com/rantav/kafka-mirror-tester
COPY *.go ./
COPY // the rest of your go files. You may copy recursive if you want
COPY vendor vendor
RUN GOPATH=/go GOOS=linux /usr/lib/go-1.11/bin/go build -a -o main .
EXPOSE 8000
ENTRYPOINT ["./main"]
You can specify a version of package to be installed in apt-get command.
e.g
apt-get install librdkafka-dev=0.11.6~1confluent5.0.1-1
If that doesn't work then I think the apt sources doesn't have version 0.11.5 of librdkafka.
You can add a repository with the right version of librdkafka in /etc/apt/sources.list as described here:
https://docs.confluent.io/current/installation/installing_cp/deb-ubuntu.html#systemd-ubuntu-debian-install
Our Dockerfile invokes a python script which copies a binary from S3 to /usr/bin. This works fine the first time. But from then on "docker-compose build" does nothing because everything is cached. This is a problem if the binary has changed.
Short of building with --no-cache, what is the best way to make sure "docker-compose build" will always pick up the new binary if there is one. We don't mind if it unnecessarily downloads the binary even if unchanged, so long as it does work then the binary has changed.
Seems like we want a Dockerfile step that always executes?
FROM ubuntu:trusty
RUN apt-get update
RUN apt-get -y install software-properties-common
RUN apt-get -y install --reinstall ca-certificates
RUN add-apt-repository ppa:fkrull/deadsnakes
RUN apt-get update && apt-get install -y \
curl \
wget \
vim \
git \
python3.5 \
python3-pip \
python3-setuptools \
libpcap0.8-dev
RUN ln -sf /usr/bin/python3.5 /usr/bin/python3
ADD . /app
WORKDIR /app
# Install Python Requirements
RUN pip3 install -r etc/python/requirements.txt
# Download/Install processor and associated libs
RUN python3 setup_processor.py
RUN mkdir -p /logs
ENTRYPOINT ["/app/entrypoint.sh"]
Where setup_processor.py downloads directly from S3 to /usr/bin.
So as of now there is no direct feature like this. But there is a workaround to your solution.
Add Build argument before your download step
ARG BUILD_ON=now
# Download/Install processor and associated libs
RUN python3 setup_processor.py
While building the image use below
docker build --build-arg BUILD_ON=$(date) ....
This will always make sure that you get a change in the ARG step and all steps cache after that will be invalidated
A feature has already been requested and being worked out on below thread

I have a RoR app that uses imagemagick specified in the Gemfile. I am using Docker's official rails image to build my image with the following Dockerfile:
FROM rails:onbuild
RUN apt-get install imagemagick
and get the following error:
Cant install RMagick 2.13.2. Cant find Magick-config in /usr/local/bundle/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
Now, that's probably because the imagemagic package is missing on the OS, even though I specified it in my Dockerfile. So I guess the bundle install command is issued before my RUN apt-get command is issued.
My question - using this base image, is there a way to ensure imagemagic is installed prior to bundling?
Do I need to fork and change the base image Dockerfile to achieve that?
you are right, the ONBUILD instructions from the rails:onbuild image will be executed just after the FROM instruction of your Dockerfile.
What I suggest is to change your Dockerfile as follow:
FROM ruby:2.2.0
RUN apt-get install imagemagick
# throw errors if Gemfile has been modified since Gemfile.lock
RUN bundle config --global frozen 1
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app
RUN apt-get update && apt-get install -y nodejs --no-install-recommends && rm -rf /var/lib/apt/lists/*
RUN apt-get update && apt-get install -y mysql-client postgresql-client sqlite3 --no-install-recommends && rm -rf /var/lib/apt/lists/*
COPY Gemfile /usr/src/app/
COPY Gemfile.lock /usr/src/app/
RUN bundle install
COPY . /usr/src/app
EXPOSE 3000
CMD ["rails", "server"]
which I made based on the rails:onbuild Dockerfile moving down the ONBUILD instructions and removing the ONBUILD flavor.
Most packages clean out the cache to save on size. Try this:
apt-get update && apt-get install imagemagick
Or spool up a copy of the container and look for yourself
docker run -it --remove <mycontainernameorid> /bin/bash
The --remove will ensure that the container is removed after you exit the shell. Once in the shell look for the package binary (or dpkg --list)
