Title: Message Title

Mads Nielsen created an issue   Jenkins / JENKINS-61931 Unable to use JNLP sidecar container without internet Issue Type: Bug Assignee: Unassigned Components: kubernetes-plugin Created: 2020-04-16 13:39 Priority: Minor Reporter: Mads Nielsen Short background: If the container name is not "jnlp" the plugin will automatically insert a JNLP container, that pulls from docker hub. Naturally this does not work within a corporate network without internet connection. If a private registry proxy is used it currently not possible to tell the Kubernetes plugin to use a different registry.  Currently there are two REALLY bad workarounds: Start Jenkins with a property: org.csanchez.jenkins.plugins.kubernetes.PodTemplateBuilder.defaultImage (BAD: requires us to maintain image version using this property) Configure docker to use private docker registry by default. This is a big change, and not recommended.  Suggestion: What about the option to prefix the default image with a custom docker registry? This could be an advanced UI option that when left alone does not change the behavior. For instance:  @VisibleForTesting static final String DEFAULT_JNLP_IMAGE = System99 .getProperty(PodTemplateStepExecution.class.getName() + ".defaultImage", "jenkins/jnlp-slave:4.0.1-1"); What if we using like a UI option could prefix the fallback "jenkins/jnlp-slave:4.0.1-1" to "$registry/jenkins/jnlp-slave:4.0.1-1". That way, the plugin would maintain the version to be used, but be able to fetch from another registry.         Add Comment   This message was sent by Atlassian Jira (v7.13.12#713012-sha1:6e07c38) -- You received this message because you are subscribed to the Google Groups "Jenkins Issues" group.
