dockerExecute in custom stage

[marcorosa]

I have a running docker cx-server instance locally (macOS Big Sur 11.2.3, docker version 20.10.5)

I set up a pipeline with a custom stage, where I would like to execute some operations in a docker container (I leave a simple apt-get update for testing)

    stage('custom-stage') {
        dockerExecute(script: this, dockerImage: 'python:3.7'){
            sh "apt-get update"
        }
    }

Yet, this stage fails with the following log

--- Begin library step of: dockerExecute ---
+ docker ps -q
Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/json: dial unix /var/run/docker.sock: connect: permission denied

are docker container stages supported by cx-server? Am I missing something?

Hi @marcorosa

thanks for reporting.

Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/json: dial unix /var/run/docker.sock: connect: permission denied

[WARNING][dockerExecute] Cannot connect to docker daemon (command 'docker ps' did not return with '0'). Configured docker image 'python:3.7' will not be used.

dockerExecute tries to run the command locally if it is not able to run it in docker.

Might be a duplicate of https://github.com/SAP/devops-docker-cx-server/issues/99

I don't have much time to look into this currently, please try running cx-server in a linux vm meanwhile.

Best,

Florian
