|
|
Creates a Jenkins Kubernetes Service Account Credential in the given credential store and domain
|
|
|
|
|
|
|
|
Defaults to the 'system' provider's store and global domain '_'
|
|
|
|
|
|
|
|
If credential id is not given as an argument, then reads from stdin, reading in ID=DESCRIPTION format
|
|
|
|
or standard shell export format - useful for shell piping
|
|
|
|
|
|
|
|
In cases where you are reading secrets from stdin, you can set the store and domain via the environment variables
|
|
|
|
\$JENKINS_SECRET_STORE and \$JENKINS_SECRET_DOMAIN
|
|
|
|
|
|
|
|
Tested on Jenkins 2.319 with Credentials plugin 2.5
|
|
|
|
|
|
|
|
Uses the adjacent jenkins_api.sh - see there for authentication details
|
|
|
|
|
|
|
|
|
|
|
|
Examples:
|
|
|
|
|
|
|
|
# create a credential with id 'my-k8s-sa':
|
|
|
|
|
|
|
|
${0##*/} my-k8s-sa 'My Description'
|
|
|
|
|
|
|
|
# or piped from standard input:
|
|
|
|
|
|
|
|
# export JENKINS_SECRET_STORE and JENKINS_SECRET_DOMAIN if using stdin but not using system global store
|
|
|
|
|
|
|
|
echo my-k8s-sa=my description | ${0##*/}
