Can we use Trigger in Gitlab community edition - gitlab

Can we use trigger in Gitlab community edition? I receive an error while trying to configure multi project pipeline.
Here is my code:
stages:
- test
testing:
stage: test
script:
- echo "Parent pipeline is working"
trigger:
- project: testgroup/childproject
- branch: master
Error: jobs:testing config contains unknown keys: trigger

Could you please share version of runner that you are running this code ? Community Edition of Gitlab allows only from 12.8.
Additionally:
Remember that jobs with trigger are compatible with script section
Do not use " - " before project and branch elements

GitLab CI - Run pipeline when the contents of a file changes

I have a mono-repo with several projects (not my design choice).
Each project has a .gitlab-ci.yml setup to run a pipeline when a "version" file is changed. This is nice because a user can check-in to stage or master (for a hot-fix) and a build is created and deployed to a test environment.
The problem is when a user does a merge from master to stage and commits back to stage (to pull in any hot-fixes). This causes ALL the pipelines to run; even for projects that do not have actual content changes.
How do I allow the pipeline to run from master and/or stage but ONLY when the contents of the "version" file change? Like when a user changes the version number.
Here is an example of the .gitlab-ci.yml (I have 5 of these, 1 for each project in the mono-repo)
#
# BUILD-AND-TEST - initial build
#
my-project-build-and-test:
stage: build-and-test
script:
- cd $MY_PROJECT_DIR
- dotnet restore
- dotnet build
only:
changes:
- "MyProject/.gitlab-ci.VERSION.yml"
# no needs: here because this is the first step
#
# PUBLISH
#
my-project-publish:
stage: publish
script:
- cd $MY_PROJECT_DIR
- dotnet publish --output $MY_PROJECT_OUTPUT_PATH --configuration Release
only:
changes:
- "MyProject/.gitlab-ci.VERSION.yml"
needs:
- my-project-build-and-test
... and so on ...
I am still new to git, GitLab, and CI/pipelines. Any help would be appreciated! (I have little say in changing the mono-repo)
The following .gitlab-ci.yml will run the test_job only if the file version changes.
test_job:
script: echo hello world
rules:
- changes:
- version

Azure build pipeline

when I run the build pipeline I am getting ##[error]File not found: 'git'. I have an agent running on a server. I installed Git on the server. The pipeline is using this agent and is tied to an Azure repo. I am using simple script as below. Please advice.
trigger:
- master
pool: 'build agent'
vmImage: 'ubuntu-latest'
steps:
- script: echo Hello, world!
displayName: 'Run a one-line script'
script: |
echo Add other tasks to build, test, and deploy your project.
echo See https://aka.ms/yaml
displayName: 'Run a multi-line script'
Here is all that you have to do if you want to create your Azure Pipeline:
Browse to Azure Pipelines and click on New Pipeline
Select Azure Repo when asked about the source of your codebase
Select your repository
Review your Pipeline YAML and click on Run
And voila, you have your first build running!
For customizing your build pipeline further, please check the various built-in build and release tasks.
Here is the YAML schema for your reference.

Troubles with .gitlab-ci.yml triggers configuration

How should I set up my .gitlab-ci.yml manifest to run builds ONLY on:
Merge Request;
Push to branch with opened merge request from it (I mean when the merge request from branch Y to branch X is already opened and some new changes are pushed to branch Y);
Push to master;
I've tried to solve it with a setting like this:
job:
only:
- triggers
- /merge-requests/
- master
except:
- branches
Regarding on the documentation here: https://docs.gitlab.com/ce/ci/yaml/README.html#only-and-except-simplified
Suddenly the error occurred on my MR page:
Could not connect to the CI server. Please check your settings and try again.
When I removed only/except restrictions from my manifest, the error was gone.
What am I doing wrong here?
My Gitlab version is: GitLab Community Edition 10.8.1
You want to run a job only on:
merge request: I don't understand what you want here
Push to branch with opened merge request from it: you have to set a special job that call the Gitlab API to control that the current branch has a MR
A job executed only on new pushed branch:
image: alpine:latest
script:
- # <-- add here the script that call Gitlab API
only:
- branches
Push to master:
A job executed only on master:
image: alpine:latest
script:
- echo "Hello world!"
only:
- master

How to control a stage play based on previous stage result without using artifacts?

We have a project hosted on an internal Gitlab installation.
The Pipeline of the project has 3 stages:
Build
Tests
Deploy
The objective is to hide or disable the Deploy stage when Tests fails
The problem is that we can't use artifacts because they are lost each time our machines reboot.
My question: Is there an alternative solution to artifacts to achieve this task?
The used .gitlab-ci.yml looks like this:
stages:
- build
- tests
- deploy
build_job:
stage: build
tags:
# - ....
before_script:
# - ....
script:
# - ....
when: manual
only:
- develop
- master
all_tests:
stage: tests
tags:
# - ....
before_script:
# - ....
script:
# - ....
when: manual
only:
- develop
- master
prod:
stage: deploy
tags:
# - ....
script:
# - ....
when: manual
environment: prod
I think you might have misunderstood the purpose of the built-in CI. The goal is to have building and testing all automated on each commit or at least every push. Having all tasks set to manual execution gives you almost no advantage over external CI tools like Jenkins or Bamboo. Your only advantage to local execution of the targets right now is having visibility in a central place.
That said there is no way to conditionally show or hide CI tasks, because it's against the basic idea. If you insist on your idea, you could look up the artifacts of the previous stages and abort the manual execution in case something is wrong.
The problem is that we can't use artifacts because they are lost each time our machines reboot
AFAIK artifacts are uploaded to the master and not saved on the runners. You should be fine having your artifacts passed from stage to stage.
By the way, the default for when is on_success which means to execute build only when all builds from prior stages succeed.

GitlabCi deploy on multiple servers

I use Gitlab runner and works fine for a single server. The gitlab-ci.yml is simple:
stages:
- test
- deploy
test:
stage: test
image: php
tags:
- docker
script:
- echo "Run tests..."
deploy:
stage: deploy
tags:
- shell
script:
- sh deploy.sh
As i said this is fine for a single server but to deploy same app on another server? I tried with same gitlab-runner config (same conf.toml) but then it was only updating one of them randomly.
Is there somehow gitlab Ci to be triggered by more than 1 runner and deploy all of them according gitlab-ci.yml?
You can register several runners (e.g. tagged serverA and serverB) from different servers and have multiple deployment jobs, each of them performed by a different runner. This is because you can set more than one tag in a job and only a runner having all the tags will be used.
stages:
- test
- deploy
test:
stage: test
image: php
tags:
- docker
script:
- echo "Run tests..."
deployA:
stage: deploy
tags:
- shell
- serverA
script:
- sh deploy.sh
deployB:
stage: deploy
tags:
- shell
- serverB
script:
- sh deploy.sh
However, take into account a situation when one of the deployment jobs fails - this would end up in you having two different versions of the code on the servers. Depending on your situation this might or might not be a problem.
Yes there is, just set up two jobs for the same stage:
stages:
- deploy
deploy:one:
stage: deploy
script:
- echo "Hello CI one"
deploy:two:
stage: deploy
script:
- echo "Hello CI two"
If necessary you can use tags on your runners to choose which one to use.
Since 2016, you now have Environments and deployments
Environments describe where code is deployed.
Each time GitLab CI/CD deploys a version of code to an environment, a deployment is created.
GitLab:
Provides a full history of deployments to each environment.
Tracks your deployments, so you always know what is deployed on your servers.
It does integrates well with Prometheis, and, with GitLab 13.11 (April 2021), you even have:
Update a deploy freeze period in the UI
In GitLab 13.2, we added the ability to create a deploy freeze period in the project’s CI/CD settings.
This capability helps teams avoid unintentional deployments, reduce uncertainty, and mitigate deployment risks.
However, it was not possible to update deploy freezes.
In GitLab 13.11, we are adding the ability to edit an existing deploy freeze. This way, you can update the freeze period to match your business needs.
See Documentation and Issue.
As shown in "gitlab-ci.yml deployment on multiple hosts", you can use YAML anchors to trigger parallel deployment on multiple environments, which means "multiple servers".
