With declarative pipelines this is pretty straight forward, just build the
Docker image like you would on your local machine using `sh` commands.
For example, in our cluster all build agents are actually the same, but
most builds run inside of a container on one of these nodes, which you've
noted (correctly) that you don't want to do, since you want to build an
image. We've simply given the "docker" label to our build agents, and our
declarative Jenkinsfile's use that label under the agent option.
For example, you could use the following Jenkinsfile to build your-app.
Note that I'm using a GIT_SHA variable here which actually doesn't resolve,
but you could easily write a pipeline shared library to provide this info.
In addition, I only like to publish master branch builds on some repos in
order to save space in our registry. You can even tell Jenkins to use
specific credentials when pushing.
pipeline {
agent { label 'docker' }
options {
ansiColor colorMapName: 'XTerm'
}
stages {
stage('Build') {
steps {
sh "docker build -t
registry.yourcompany.com/company/your-app:${GIT_SHA} ."
}
}
stage('Publish') {
when {
branch 'master'
}
steps {
withDockerRegistry([credentialsId: 'registry-creds', url:
'https://registry.yourcompany.com']) {
sh "docker push
registry.yourcompany.com/company/your-app:${GIT_SHA}"
}
}
}
}
}
