How to "docker login" to Artifactory from Jenkins

Question

In my Jenkins job I need to login to Artifactory

I've created a global credentials called "Docker_artifactory_creds"

In job I created bindings for that creds

to use them in an "Execute shell" step as

docker login artifacts.some_custom.com -u ${ARTIFACTORY_USER} -p ${ARTIFACTORY_PASSWD}

but that doesn't work (with the same creds passed as row text this line works). I see following logs:

The following environment variables were removed by 'Only Keep Specified Environment Variables': ARTIFACTORY_PASSWD, ARTIFACTORY_USER, Branch, BUILD_CAUSE, ..., WORKSPACE, WORKSPACE_TMP Removing login credentials for artifacts.some_custom.com
Error: Cannot perform an interactive login from a non TTY device

Why my credentials were ignored/removed?

Answer 1

this error from https://plugins.jenkins.io/safe-batch-environment-filter/ plugin

in freestyle: not sure there is a way to do it, only add your job to exclude list in jenkins global config

in Jenkinsfile: you need to wrap your code with

keepEnv(['ARTIFACTORY_USER', 'ARTIFACTORY_PASSWD']) {
  docker login artifacts.some_custom.com -u ${ARTIFACTORY_USER} -p ${ARTIFACTORY_PASSWD}
}

ps also need to add withCredentials or what you use to get this creds to env variable

also jenkins has this feature: https://issues.jenkins.io/browse/JENKINS-62014 https://github.com/jenkinsci/workflow-durable-task-step-plugin/pull/137

assume you use freestyle jenkins job

in job config -> build steps -> execute shell -> advanced -> environment filters -> only keed specified environment variables

there you will find setting Environment variables to retain you need to add your variables there

Whitespace separated, case insensitive list of environment variables that will be retained, i.e. not removed from the environment of this build step or reset to their default.

by default jenkins will remove variable
