We are currently trying to support multi-arch image builds on our jenkins runners.
The runner is hosted on an EC2 spot instance on AWS using a custom AMI of Amazon Linux 2 which contains some build requirements. Which now already includes a configured buildx builder.
But, when running a pipeline that contains a docker buildx build ... command the jenkins pipeline fails complaining about the fact that the default docker builder does not support multi-platform builds. Meaning that the builder doesn't exist somehow in the context of the pipeline.
I have installed the buildx builder in the AMI using following commands:
docker run --privileged --rm tonistiigi/binfmt --install all
docker buildx create --name multi-arch-builder --use
Creating a custom EC2 instance using this AMI and executing the same docker buildx build ... command that gets executing in the jenkins pipeline works fine.
I also added a shell command to see if the builder is even visible for the jenkins pipeline:
docker buildx use multi-arch-builder
This results in an error, because the builder could not be found.
The only other solution I currently have is to add the creation of the buildx builder to each pipeline... Which is not ideal.

Hello i want to build some maven projects in docker.
While the build process some more docker containers will be spawned so i want to isolate them inside... docker.
for Example:
Develop-branch[database-container, core-container]
Feature(1..n)[database-container, core-container]
I tried to use Jenkins docker plugin and configured the linux-server as cloud using unix socket.
For the building container i use docker:dind and installed inside maven java and git.
FROM docker:dind
RUN apk add openjdk11 maven git
compailing is working but if it comes to the
build stepp calling docker i got the Error:
[ERROR] DOCKER> Cannot create docker access object [No such file or directory]
I have been playing around with Jenkins, and I'm now able to connect github and set triggers. I want to build my code using make and docker, however when i execute make or docker in the shell, they are not found. How do I configure Jenkins' build step to run make and docker
I would install make and the docker daemon on your Jenkins server. This will allow you to build and push docker images from within your Jenkins build pipelines using the Executable Shell Build task. You will also be able to run make commands there as well.
docker build -t <USER>/<REPO_NAME>:<TAG> .
docker push <USER>/<REPO_NAME>:<TAG>
There are also Jenkins plugins available for building your docker images too.
I would NOT recommend running Jenkins using a Docker container, then running Docker inside that container. This is known as Docker in Docker(aka. DinD), and should be avoided for the reasons stated in this article.
You can install Docker on the same machine where your jenkins is running.
Or you can run a docker container which contains both jenkins and docker.
If you purpose is to learn jenkins, I suggest running Jenkins within a docker and Docker daemon on your host machine.
just have Docker installed on your host machine.
then issue the command which runs
docker run \
--rm -u root -p 8080:8080 -v /var/run/docker.sock:/var/run/docker.sock --name myjenkinsserver jenkinsci/blueocean
then you are ready to go.
add a pipeline job as follows:
pipeline {
agent { docker 'gcc:latest' }
stages {
stage('build') {
steps {
sh 'make --version'
}
}
}
}
now you can run make commands.
In general, it is better to run jenkins jobs on Jenkins slave machines or in other terms, Jenkins agents. You can create custom Jenkins agents which include necessary tools, in your case, such as make.
I've got a jenkins declarative pipeline build that runs gradle and uses a gradle plugin to create a docker image. I'm also using a dockerfile agent directive, so the entire thing runs inside a docker container. This was working great with jenkins itself installed in docker (I know, that's a lot of docker). I had jenkins installed in a docker container on docker for mac, with -v /var/run/docker.sock:/var/run/docker.sock (DooD) per https://jpetazzo.github.io/2015/09/03/do-not-use-docker-in-docker-for-ci/. With this setup, the pipeline docker agent ran fine, and the docker build command within the pipeline docker agent ran fine as well. I assumed jenkins also mounted the docker socket on its inner docker container.
Now I'm trying to run this on jenkins installed on an ec2 instance with docker installed properly. The jenkins user has the docker group as its primary group. The jenkins user is able to run "docker run hello-world" successfully. My pipeline build starts the docker agent container (based on the gradle image with various things added) but when gradle attempts to run the docker build command, I get the following:
* What went wrong:
Execution failed for task ':docker'.
> Docker execution failed
Command line [docker build -t config-server:latest /var/lib/****/workspace/nfig-server_feature_****-HRUNPR3ZFDVG23XNVY6SFE4P36MRY2PZAHVTIOZE2CO5EVMTGCGA/build/docker] returned:
Cannot connect to the Docker daemon. Is the docker daemon running on this host?
Is it possible to build docker images inside a docker agent using declarative pipeline?
Yes, it is.
The problem is not with Jenkins' declarative pipeline, but how you're setting up and running things.
From the error above, looks like there's a missing permission which needs to be granted.
Maybe if you share what your configuration looks like and how your're running things, more people can help.
I am using Jenkins to make build of project, but now my client wants to make builds inside of a Docker image. i have installed docker on server and its running on 172.0.0.1:PORT. I have installed Docker plugin and assigned this TCP URL to Docker URL. I have also created an image with the name jenkins-1
In configure project I use Build environment Build with Docker Container and provide image name. and then in Build in put Execute Shell and then Build it
But it gives the Error:
Pull Docker image jenkins-1 from repository ...`
$ docker pull jenkins-1`
Failed to pull Docker image jenkins-1`

I just have run into the same issue. There is a 'Verbose' check-box in the configuration of build environment after selecting 'Advanced...' link to expand on the error details:
CloudBees plug-in Verbose option
In my case I ran out of space downloading the build Docker images. Expanding ec2 volume has resolved the issue.
But there is an ongoing trouble with space as docker does not auto cleans images and I have ended up adding a manual cleanup step into the build:
docker volume ls -qf dangling=true | xargs -r docker volume rm

I want to run a docker image create command from a Jenkins job which is running native on my machine with VM running Docker.
I've installed docker build step plugin and in manage Jenkins page command fails when I try to configure docker using url and version, it says:
Test Connection Something went wrong, cannot connect to
http://192.168.99.100:2376, cause: null
I've got this docker url from the docker-machine env command.
In the version field, I tried both REST API version and Docker version, but no success.
Is it possible to call Docker from outside the docker VM and from a Jenkins job? If yes how to configure it in Jenkins?
