|
Creates or Updates a Jenkins SSH Key Credential in the given credential store and domain
|
|
|
|
Defaults to the 'system::system::jenkins' provider store and global domain '_'
|
|
|
|
If credential id, user and private_key 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 '-ssh-key' 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:
|
|
|
|
# create a credential with id 'hari-ssh-key', username 'hari' and load the private key contents from my ~/.ssh/id_rsa file:
|
|
|
|
${0##*/} hari-ssh-key hari ~/.ssh/id_rsa
|
|
|
|
# with a description, leaving the store and domain as the default global one:
|
|
|
|
${0##*/} hari-ssh-key hari ~/.ssh/id_rsa '' '' 'My SSH Key'
|
|
|
|
# or piped from standard input:
|
|
|
|
#export JENKINS_SECRET_STORE and JENKINS_SECRET_DOMAIN if using stdin if not using system global store
|
|
|
|
echo hari=~/.ssh/id_rsa | ${0##*/}
