Jenkins Configuration-as-Code plugin

Rodolfo Boer

@move-z

sorry i'll try to improve formatting

it loads fine and all the items are set in the config except for the securityRealm (for which I already installed the active active directory plugin)

i see nothing in the logs suggesting there are problems with the entry, it just has no effect

i also tried with this simpler config instead of activeDirectory but it makes no difference:

  securityRealm:
    local:
      allowsSignup: true

an interesting detail: if I go to the configuration-as-code settings page and click "reload existing configuration", it actually gets loaded, both the local and the active directory version, so the problem seems to be only at startup

final note: i'm using jenkins 2.176.3 (current stable), active directory plugin 2.16 and configuration as code plugin 1.30

i think the simplest solution would be to trigger a reload after startup using the cli or an post

any comments from the experts?

Joseph Petersen

@Jetersen

@move-z what if you configure it in UI first and use the export feature?

@move-z I haven't used the active directory plugin. Have you considered using the ldap plugin instead?

jenkins:
  securityRealm:
    ldap:
      cache:
        size: 100
        ttl: 30
      configurations:
      - groupSearchBase: "OU=Jenkins,OU=Security Groups,OU=DevOps"
        groupSearchFilter: "(&(cn={0})(objectclass=group))"
        ignoreIfUnavailable: true
        inhibitInferRootDN: false
        managerDN: "jenkinsldap"
        managerPasswordSecret: "${LDAP_PASSWORD}"
        rootDN: "dc=company,dc=io"
        server: "ldaps://ldap.company.io:3269"
        userSearch: "sAMAccountName={0}"
      disableMailAddressResolver: false
      groupIdStrategy: "caseInsensitive"
      userIdStrategy: "caseInsensitive"

DevOps is a culture not a team :wink:

Joseph Petersen

@Jetersen

@timja legacy :sob: The team is called BAT nowadays and we still try to spread DevOps :laughing:

Tim Jacomb

@timja

business acceptance testers? :wink:

batman?

Joseph Petersen

@Jetersen

batman :laughing:

We have a whole Marvel vs DC Comics for all of our team names. And those who have adopted DevOps are called Batmen :)
The acronym for bat is Build Automate and Test :sweat_smile:

Hello guys.. din not looked at plugin development for some time.. maybe in meantime pipeline support was added?

Tim Jacomb

@timja

nope, but a webhook was added for reloading

without needing to auth

just pass a token in the url which is configured on startup

@nguyenhugh

Hello All, is it possible to have secrets lives outside of Jenkins.yaml file and a separate yaml which can have configurations for like Role Base Strategy and such?

Oleg Nenashev

@oleg-nenashev

@nguyenhugh yes to both. For secrets see https://github.com/jenkinsci/configuration-as-code-plugin#secret-sources . Regarding a separate YAML file, you can point JCasC to a directory which contains multiple YAML files. In such case all YAML files will be applied

I would like to ask two questions: 1) How to set git-lfs using jcac? https://devops.stackexchange.com/q/9225/210 and 2) How to implement shallow clone https://devops.stackexchange.com/q/9229/210

Joseph Petersen

@Jetersen

@030 Your seem to be using a old version of git :sweat: It should be available as traits under git.

030

@030

@casz The git-lfs command is included on the system. The issue is that GitLFSPull seems to be omitted in the Jenkins job dsl: https://jenkinsci.github.io/job-dsl-plugin/#path/job-scm-git-extensions

Joseph Petersen

@Jetersen

what version of git do you have installed @030

Ignacio Tolstoy

@naxhh

Hi everyone! we are using casc for our new jenkins. We have a very old dated jenkins in our company and we are moving as much as we can to have things in code.
For this we use casc with a dockerfile and job-dsl with pipelines for job configurations

Now we are facing how we will deploy this system. The main idea was to start a fresh docker on each deploy since each docker version will have different configurations.
We face 2 "problems" here:

Build history and logs
we loose all of this, this can be workaround with some metrics (datadog in our case) since regarding history we care more about when something started failling and not the logs per se.
API keys
We switch from one docker to another during deploy. For the user this is a weird experience.
So we want to notify the user X given time before the change. For this, we tell Jenkins A to stop running new jobs. When there are no jobs running anymore we switch to the other version.

In order to do this, we use the API and a user token. The problem is that we use LDAP plugin to make auth. This means we need a way to generate the user token in the first place. We tried different approaches but all of them look really weird...
How would you approach this last point?

Also interested in how other people is deploying CASC

Tim Jacomb

@timja

Can you log in as the user once and then create the api token via API?
there's a PR to hopefully make the second bit easier:
jenkinsci/jenkins#4027

RE: 1
We keep the build history via a docker volume and just upgrade on top of it, if there's every any issues we can just delete the volume and start from scratch

Ignacio Tolstoy

@naxhh

I don't think you can login to the api using user/pass when using ldap, but i'll ask my team mate since he is doing it.
Regarding the second, what is the path of the volume? that may work for us, but I thought config and logs where under the same path (my knowledge of jenkins is not that strong)

Tim Jacomb

@timja

/var/jenkins_home I believe

config is under the same path as well, but casc will just override it

Ignacio Tolstoy

@naxhh

ok! that last part is the one that i didn't know! thanks @timja!

Regarding the API, no, we can't use user:password for auth with ldap. That's why we need the api token, but there's no way to generate it unless we manually create it or a job does it for us (if it's possible)
That last approach is the one we are testing, but feels very hacky

Regarding jenkinsci/jenkins#4027 it looks that will be what we are looking for, so I'll keep an eye on it.

Can you set the meeting so we can start it without you?

no worries, was fine

@030

@casz git version 2.17.1 and git lfs returns the help menu of git lfs. I found a workaround to enable git-lfs in the UI and updated the Q&A on devops SE that was mentioned earlier.
