How can a Jenkins user authentication details be "passed" to a script which uses Jenkins API to create jobs?

Question

I have a script that delete and re-create jobs through curl HTTP-calls and I want to get rid of any hard-coded "username:password". E.g. curl -X POST $url --user username:password

Considerations:

• Jenkins CLI (probably not an option). One should be able to achieve the same with the CLI as with Jenkins API (creating jobs etc) but as far as I understand Jenkins CLI is not a good alternative for me since jobs created with will only appear in Jenkins after restarting or a "Reload Configuration from Disk", and that would cancel any other running jobs.

• API token. Can't find out how to get the user token and then pass it as a parameter to the script, but that may be a solution..

Solution 1

Try this way: (for example delete the job)

curl --silent --show-error http://<username>:<api-token>@<jenkins-server>/job/<job-name>/doDelete

The api-token can be obtained from http://<jenkins-server>/user/<username>/configure.

Solution 2

This worked for me:

curl -u $username:$api_token -FSubmit=Build 'http://<jenkins-server>/job/<job-name>/buildWithParameters?environment='

API token can be obtained from Jenkins user configuration.

Solution 3

• With Jenkins CLI you do not have to reload everything - you just can load the job (update-job command). You can't use tokens with CLI, AFAIK - you have to use password or password file.

• Token name for user can be obtained via http://<jenkins-server>/user/<username>/configure - push on 'Show API token' button.

• Here's a link on how to use API tokens (it uses wget, but curl is very similar).

Solution 4

I needed to explicitly add POST in the CURL command:

curl -X POST http://<user>:<token>@<server>/safeRestart

I also have the SafeRestart Plugin installed, in case that makes a difference.

Solution 5

If you want to write a script to automate creation of jobs using the Jenkins API, you can use one of the API clients to do that. A ruby client for Jenkins is available at https://github.com/arangamani/jenkins_api_client

gem install jenkins_api_client

require "rubygems"
require "jenkins_api_client"

# Initialize the client by passing in the server information
# and credentials to communicate with the server
client = JenkinsApi::Client.new(
  :server_ip => "127.0.0.1",
  :username => "awesomeuser",
  :password => "awesomepassword"
)

# The following block will create 10 jobs in Jenkins
# test_job_0, test_job_1, test_job_2, ...
10.times do |num|
  client.job.create_freestyle(:name => "test_job_#{num}")
end

# The jobs in Jenkins can be listed using
client.job.list_all

The API client can be used to perform a lot of operations.
