|
|
Updates a Jenkins Username/Password Credential in the given credential store and domain
|
|
|
|
|
|
|
|
Defaults to the 'system::system::jenkins' provider store and global domain '_'
|
|
|
|
|
|
|
|
If credential id, user and password aren't given as arguments, then reads from stdin, reading in KEY=VALUE
|
|
|
|
or standard shell export format - useful for piping from tools like aws_csv_creds.sh
|
|
|
|
|
|
|
|
If standard input does not have an id field, the id will be generated from the username lowercased with -user-pass appended.
|
|
|
|
|
|
|
|
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_cli.sh - see there for authentication details
|
|
|
|
|
|
|
|
|
|
|
|
Examples:
|
|
|
|
|
|
|
|
# update a credential with id 'hari-user-pass' to have username 'hari' and password 'myNewPassword':
|
|
|
|
|
|
|
|
${0##*/} hari-user-pass hari myNewPassword
|
|
|
|
|
|
|
|
# with a description, leaving the store and domain as the default global one:
|
|
|
|
|
|
|
|
${0##*/} hari-user-pass hari myNewPassword '' '' 'My Updated Username + Password'
|
|
|
|
|
|
|
|
# or piped from standard input:
|
|
|
|
|
|
|
|
#export JENKINS_SECRET_STORE and JENKINS_SECRET_DOMAIN if using stdin but not using system global store
|
|
|
|
|
|
|
|
echo 'hari=myNewPassword' | ${0##*/}
