I have an Jenkins Server running in an docker container and have access to docker an the host system, so far it is working well. Now I want to set up a pipeline testing an script inside an docker container.
Jenkinsfile:
pipeline {
agent { docker 'nginx:1.11' }
stages {
stage('build') {
steps {
sh 'nginx -t'
}
}
}
}
Error Message:
> + docker pull nginx:1.11
>
> Warning: failed to get default registry endpoint from daemon (Got
> permission denied while trying to connect to the Docker daemon socket
> at unix:///var/run/docker.sock: Get

My problem is that jenkins needs to run the docker command with sudo, but how to say the agent running the command with sudo?
