i have created the docker image that installs java,jenkins,jenkins-cli. now i need to pass some argument through jenkins-cli, so i need to launch jenkins-cli. How do i do it? i have no idea how it launches.
Here is my script
FROM ubuntu:14.04
RUN apt update; \
apt upgrade -y; \
apt install -y default-jdk curl wget git maven nano unzip; \
apt-get clean
ENV JAVA_HOME /usr
ENV PATH $JAVA_HOME/bin:$PATH
RUN apt-get autoclean $$ apt-get clear cache
RUN apt-get -yqq update
RUN apt-get -yqq --no-install-recommends install git bzip2 curl unzip
RUN apt-get update
# copy jenkins war file to the container
ADD http://mirrors.jenkins.io/war-stable/2.107.1/jenkins.war /opt/jenkins.war
RUN chmod 644 /opt/jenkins.war
ENV JENKINS_HOME /jenkins
# configure the container to run jenkins, mapping container port 8080 to that host port
ENTRYPOINT ["java", "-jar", "/opt/jenkins.war"]
EXPOSE 8080
RUN mkdir /jenkins/
RUN echo 2.107.1 > /jenkins/jenkins.install.UpgradeWizard.state
RUN echo 2.107.1 > /jenkins/jenkins.install.InstallUtil.lastExecVersion
#jenkin-cli installation
RUN cd /tmp && curl --insecure -OL http://192.168.99.100:8080/jnlpJars/jenkins-cli.jar
ADD /tmp/jenkins-cli.jar /opt/jenkins/jenkins-cli.jar
RUN chmod 644 /opt/jenkins-cli.jar
WORKDIR /opt/jenkins
ENTRYPOINT ["java", "-jar", "jenkins-cli.jar", "-noCertificateCheck", "-noKeyAuth"]
CMD ["--help"]
this is error:
Step 19/24 : RUN cd /tmp && curl --insecure -OL http://192.168.99.100:8080/jnlpJars/jenkins-cli.jar
---> Using cache
---> 9a6210009f84
Step 20/24 : ADD jenkins-cli.jar /opt/jenkins/jenkins-cli.jar
ADD failed: stat /mnt/sda1/var/lib/docker/tmp/docker-builder945232568/jenkins-cli.jar: no such file or directory[1]
This error is causing me for may other build too,if i can find best solution i can solve my all other problems.
2nd question is, is my scripting for my current problem is right? How can i modify?
Can anyone help me with this..?
thank u in advance
You forgot to create the /opt/jenkins folder
Change
ADD http://mirrors.jenkins.io/war-stable/2.107.1/jenkins.war /opt/jenkins.war
to
RUN mkdir /opt/jenkins
ADD http://mirrors.jenkins.io/war-stable/2.107.1/jenkins.war /opt/jenkins/jenkins.war
Given your cli tool is available from within your container with a simple command such as cli-tool_command this should work:
docker run --rm -it {container_image_name} {cli_tool_command} {cli_tool_args}

I have a docker file in which I do wget to copy something in the image. But the build is failing giving 'wget command not found'. WHen i googled I found suggestions to install wget like below
RUN apt update && apt upgrade
RUN apt install wget
Docker File:
FROM openjdk:17
LABEL maintainer="app"
ARG uname
ARG pwd
RUN useradd -ms /bin/bash -u 1000 user1
COPY . /app
WORKDIR /app
RUN ./gradlew build -PmavenUsername=$uname -PmavenPassword=$pwd

RUN wget https://www.yourkit.com/download/docker/YourKit-JavaProfiler-${YOURKIT_VERSION}-docker.zip --no-check-certificate -P /tmp/ && \
unzip /tmp/YourKit-JavaProfiler-${YOURKIT_VERSION}-docker.zip -d /usr/local && \
mv /usr/local/YourKit-JavaProfiler-${YOURKIT_VERSION} /usr/local/$POLARIS_YK_DIR && \

EXPOSE 10001
EXPOSE 8080
EXPOSE 5005

ENTRYPOINT ["sh", "/docker_entrypoint.sh"]
On doing this I am getting error app-get not found. Can some one suggest any solution.
The openjdk image you use is based on Oracle Linux which uses microdnf rather than apt as it's package manager.
To install wget (and unzip which you also need), you can add this to your Dockerfile:
RUN microdnf update \
&& microdnf install --nodocs wget unzip \
&& microdnf clean all \
&& rm -rf /var/cache/yum
The commands clean up the package cache after installing, to keep the image size as small as possible.
I built a docker image using Dockerfile with Python and some libraries inside (no my project code inside). In my local work dir, there are some scripts to be run on the docker. So, here what I did
$ cd /path/to/my_workdir
$ docker run -it --name test -v `pwd`:`pwd` -w `pwd` my/code:test python src/main.py --config=test --results-dir=/home/me/Results
The command python src/main.py --config=test --results-dir=/home/me/Results is what I want to run inside the Docker container.
However, it returns,
/home/docker/miniconda3/bin/python: /home/docker/miniconda3/bin/python: cannot execute binary file
How can I fix it and run my code?
Here is my Dockerfile

Try making the file executable before running it.
as John mentioned to do in the dockerfile
FROM python:latest
COPY src/main.py /usr/local/share/
RUN chmod +x /usr/local/share/src/main.py #<-**--- just add this also
# I have some doubts about the pathing
CMD ["/usr/local/share/src/main.py", "--config=test --results-dir=/home/me/Results"]
You can run a python script in docker by adding this to your docker file:
FROM python:latest
COPY src/main.py /usr/local/share/
CMD ["src/main.py", "--config=test --results-dir=/home/me/Results"]
in while i'm trying to build an image im getting following error.
In this image i need to download jenkins, run jenkins in background and then download jenkins-cli, then i have to give my input to cli.

QUESTIONS
Is jenkins-cli downloading
which directory its unable to locate
do i need to run jenkins in background to download jenkins-cli aand
work and How to do it?
and solutions for it
Thank u in advance

ENTRYPOINT ["java","-jar","/jcli/jenkins-cli.jar","-noCertificateCheck","-noKeyAuth"]
CMD ["--help"]
you can try after updating your Dockfile entrypoint as
ENTRYPOINT ["java","-jar","/opt/tmp/jenkin-cli.jar","-noCertificateCheck","-noKeyAuth"]
and also remove following lines:
RUN chmod 644 jenkins-cli.jar
WORKDIR /opt/tmp/jenkins-cli
COPY opt/tmp/jenkins-cli.jar ./jenkins-cli
This looks like a typo error. In your curl command i.e step 19/27, --output is /opt/tmp/jenkin-cli.jar it needs to be /opt/tmp/jenkins-cli.jar.
Error states that it is unable to locate the file /opt/tmp/jenkins-cli.jar because you created the file with name jenkin-cli.jar & not jenkins-cli.jar.
Now the 2nd mistake is you are missing / before opt and moreover,
COPY works from host to container & not within the container. In that case, you don't need to download the CLI to create a container and image.
I am trying to build a docker image using the following docker file.
FROM ubuntu:latest
# Replace shell with bash so we can source files
RUN rm /bin/sh && ln -s /bin/bash /bin/sh
# Update packages
RUN apt-get -y update && apt-get install -y \
curl \
build-essential \
libssl-dev \
git \
&& rm -rf /var/lib/apt/lists/*
ENV APP_NAME testapp
ENV NODE_VERSION 5.10
ENV SERVE_PORT 8080
ENV LIVE_RELOAD_PORT 8888
# Install nvm, node, and angular
RUN (curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.31.1/install.sh | bash -) \
&& source /root/.nvm/nvm.sh \
&& nvm install $NODE_VERSION \
&& npm install -g angular-cli \
&& ng new $APP_NAME \
&& cd $APP_NAME \
&& npm run postinstall
EXPOSE $SERVE_PORT $LIVE_RELOAD_PORT
WORKDIR $APP_NAME
EXPOSE 8080
CMD ["node", "-v"]
But I keep getting an error when trying to run it:
docker: Error response from daemon: Container command 'node' not found or does not exist..
I know node is being properly installed because if I rebuild the image by commenting out the CMD line from the docker file
#CMD ["node", "-v"]
And then start a shell session
docker run -it testimage
I can see that all my dependencies are there and return proper results
node -v
v5.10.1
.....
ng -v
angular-cli: 1.0.0-beta.5
node: 5.10.1
os: linux x64
So my question is. Why is the CMD in Dockerfile not able to run these and how can I fix it?
When using the shell to RUN node via nvm, you have sourced the nvm.sh file and it will have a $PATH variable set in it's environment to search for executable files via nvm.
When you run commands via docker run it will only inject a default PATH
docker run <your-ubuntu-image> echo $PATH
docker run <your-ubuntu-image> which node
docker run <your-ubuntu-image> nvm which node
Specifying a CMD with an array execs a binary directly without a shell or a $PATH to lookup.
Provide the full path to your node binary.
CMD ["/bin/node","-v"]
It's better to use the node binary rather than the nvm helper scripts due to the way dockers signal processing works. It might be easier to use the node apt packages in docker rather than nvm.
In Jenkins I installed Docker build step plugin.
In Jenkins, created job and in it, executed docker command selected build image. The image is created using the Dockerfile.The Dockerfile is :
FROM ubuntu:latest

EXPOSE 80
EXPOSE 27017
Then I tried to create the container and container is created.
When I tried to start the container, the container is not running.
When I checked with command:
docker ps -a
, it shows status as created only.
Its not in running or Exited state.
The output of docker ps -a is:
docker ps -a

How to start the container using jenkins?
It depends on your container main command (ENTRPOINT + CMD)
A created state (for non data-volume container) means the main command failed to execute.
Try a docker logs <container_id> to see if there is any error message recorded.
CMD ["sh", "/home/servicestart.sh"] should be:
CMD ["/home/servicestart.sh"]
(The default ENTRYPOINT for Ubuntu should be ["sh", "-c"], so no need to repeat an "sh")
