I have a drone.yml running 3 pipelines on my github repo. One for pullrequests that get run as soon as some one submits a pull request, a pipeline for releases that makes docker containers and outputs a docker-compose, and now I'm making a pipeline that runs integration tests after a merge into master.
One of the steps is that it updates a test server, which is making the task challenging. Is there a way to force this specific drone pipeline to only run if there isn't any other of this pipeline running?
You can used depends_on to force the order of the pipelines execution.

The company I work for has a self hosted Gitlab CE server v13.2.1.
For a specific project I've setup the CI jobs to build according to the following workflow :
If a commit has been pushed to the main branch
If a merge request has been created
If a tag has been pushed
Every day at midnight to build the main branch (using scheduled pipelines)
Everything works fine. The only thing I would like to improve is that the nightly builds are performed even if the main branch has not been modified (no new commit).
I had a look to the Gitlab documentation to change my workflow: rules in the .gitlab-ci.yml file but I didn't find anything relevant.
The gitlab runner is installed in a VM and is setup as a shell executor. I was thinking of creating in the home directory a file to store the last commit ID. I'm not a big fan of that solution, because :
it's a ugly fix.
The pipeline will be triggered by Gitlab even if it does nothing. This will pollute the pipeline list.
Is there any way to setup the workflow: section to perform this so the pipeline list won't contain unnecessary pipeline ?
What is the best practice to run 2 pipelines on the same project?
pipeline_1:
build jars jobs and run tests jobs
should be run each merge request.
pipeline_2:
build jars jobs and run e2e tests jobs
should be run every day.
Can I create 2 pipelines on the same project?
where one scheduled and second on each merge request and part of build jobs are common for both pipelines, but tests jobs are different.
Each "stage" in the .gitlab-ci.yml file is considered a pipeline, so this should just be a matter of adding the correct scripting for each stage.
On pipeline_2, you could set it to a pipeline schedule and make it dependent on the success of pipeline_1. That's what I would do.

I'm using a webhook to trigger my Gitlab pipeline. Sometimes, this trigger is triggered a bunch of times, but my pipelines only has to run the last one (static site generation). Right now, it will run as many pipelines as I have triggered. My pipelines takes 20 minutes so sometimes it's running the rest of the day, which is completely unnecessary.
https://docs.gitlab.com/ee/ci/yaml/#interruptible and https://docs.gitlab.com/ee/user/project/pipelines/settings.html#auto-cancel-pending-pipelines only work on pushed commits, not on triggers
A similar problem is discussed in gitlab-org/gitlab-foss issue 41560
Example of a use-case:
I want to always push the same Docker "image:tag", for example: "myapp:dev-CI". The idea is that "myapp:dev-CI" should always be the latest Docker image of the application that matches the HEAD of the develop branch.
However if 2 commits are pushed, then 2 pipelines are triggered and executed in paralell. Then the latest triggered pipeline often finishes before the oldest one.
As a consequence the pushed Docker image is not the latest one.
Proposition:
As a workaround for *nix you can get running pipelines from API and wait until they finished or cancel them with the same API.
In the example below script checks for running pipelines with lower id's for the same branch and sleeps.
jq package is required for this code to work.
Or:
Create a new runner instance
Configure it to run jobs marked as deploy with concurrency 1
Add the deploy tag to your CD job.
It's now impossible for two deploy jobs to run concurrently.
To guard against a situation where an older pipeline may run after a new one, add a check in your deploy job to exit if the current pipeline ID is less than the current deployment.
Slight modification:
For me, one slight change: I kept the global concurrency setting the same (8 runners on my machine so concurrency: 8).
But, I tagged one of the runners with deploy and added limit: 1 to its config.
I then updated my .gitlab-ci.yml to use the deploy tag in my deploy job.
Works perfectly: my code_tests job can run simultaneously on 7 runners but deploy is "single threaded" and any other deploy jobs go into pending state until that runner is freed up.
I'm trying to run a pipeline with two stages. The first stage creates a zip file and the second stage executes a http curl POST for that file. If the curl succeeds, the pipeline is completed.
The problem is that gitlab only exposes the zip file AFTER the pipeline has completed - which means the zip file from the previous pipeline gets sent instead.
I've tried using artifacts and dependencies, but it seems the http url is only exposed for completed pipelines. I tried using the url of the specific job that executed the build stage, but it didn't work either.
Does anyone know how to access an artifact by URL, before pipeline completion?
i was unable to find a way to access the artifact remotely before the pipeline had completed. sad face.
i have a workaround though - i moved the deploy stage to a separate pipeline. so the first pipeline just executes the build (generating the artifacts) and then triggers the second pipeline. the second pipeline is then able to access the artifacts of the first pipeline and it just executes a deploy stage. happy face.
I use drone as CI and want to know how I can disable simultaneous build. What's happening is that when I submit two commits to git repo, drone will trigger two build on each of the submit. How can I let the second build wait until the first one finish?
Regarding the open source version of Drone: set the DOCKER_MAX_PROCS environment variable of your drone agent to 1, i.e. docker run -e DOCKER_MAX_PROCS=1 [...] drone/drone:0.5 agent. The agent will run one build concurrently, other builds will queue up.
See the Installation Reference section in the readme for more info.
