Now, to create a webhook, open your project and on the left hand side go to Settings -> Webhook and configure your webhook like this:įor easy copy and paste, take this template and fill in your Test So go to the admin panel and in the "Outbound Requests" section, add "jenkins" to the "Whitelist to allow requests to the local network from hooks and services".ĭon't check the box that allows all adresses in the local network! Just add jenkins to the whitelist But we want to allow it to do so with Jenkins, because otherwise that would render this whole mechanic moot for us. Gitlab is smart, they don't want to permit Webhooks to spam the local network of a gitlab instance to prevent damage. This is it, the end of the road, we are near the finish line! Save it somewhere you can copy it from later, because that little bugger is gone, once you navigate away from the current page.Īs a nice benefit, you can monitor later on how many times the token has been used. Now we need an API-Token to authenticate with Jenkins in HTTP-Requests, without having to use the actual password of our admin-user. To enable Jenkins-Jobs to be triggered via HTTP-Request, you need to do a few things.įirst, check the following box in your job and define a secret token. It should be a success, and you can docker pull it anytime from our registry :)Īlright, on to the home-stretch! We are done with all the prep-work, so let's get to what we actually wanted to achieve. Now you can trigger the build and enjoy the show! Now that our shiny new Gitlab is running, let's create a demo repository here and commit the following demo Dockerfile to it: More info on the Gitlab Docker Images can be found here Then you are ready to create some repos :) The Gitlab omnibus image takes a while to boot, you can monitor it via docker logs -f gitlab to see when it's ready to use.Īfter it's booted up, you can open the Gitlab UI in your favorite browser and set a password for the user root. Note: Again, you'll have to set everything up again, if you restart the containers without their data persisted somewhere If you don't want the containers to play around in your filesystem, just remove the mounts. Of course, I will update this post accordingly, once I got gitlab to work smoothly on alpine :) If ! groups jenkins | grep -q docker thenįi #If you run on MacOS if ! groups jenkins | grep -q staff thenįi # Add call to gosu to drop from root user to jenkins user # when running original entrypoint set - gosu jenkins " " fi # replace the current pid 1 with original entrypoint exec " "Įnter fullscreen mode Exit fullscreen modeĪnd yes, I know, this breaks the rule of "build it yourself", but I can't for the life of me get gitlab running on alpine yet, so for this demonstration I beg you to bear with me this one time. gosu-deps \ĭpkgArch = " $(dpkg -print-architecture | awk -F- ' -o docker # Install Gosu ENV GOSU_VERSION 1.12 RUN set -eux \Īpk add -no-cache -virtual. Which thankfully, is very easy to do!įROM alpine USER root RUN apk add -no-cache \ If you want dns-resolution for containers by their name, you need to create a custom bridge network. I could go on a tangent and tell you the grand story, but in short, the default bridge network does no dns resolution because of reasons.
