I have a pipeline where I want to:
provision some resources,
run some tests,
tear down the resources.
I want the tear down task, in step 3, to run regardless of whether tests passed or failed, in step 2. As far as I’ve understoood runAfter only runs a task, if the previous task succeeded.
I tried looking into Conditions, but can’t seem to find an example…
Anything else I can use or some example someone could point me to ?

It turns out this is not yet supported in Tekton, at the time of writing.
It is, however, work-in-progress in the tektoncd/pipeline project, in this PR.

I want to be able to reuse the deployment variable on my bitbucket pipeline but this is not allowed. Is there any way to combine the steps?
pipelines:
default:
- step: *build
branches:
master:
- step: *build
- step:
<<: *deploy1
name: Deployment 1
deployment: Production
- step:
<<: *deploy2
name: Deployment 2
deployment: Production
I see that bitbucket has this on the roadmap for bb pipelines. I'm currently trying to do something similar. If I find a solution or something works for me. I'll post my solution.
I have self-hosted agents on multiple environments that I am trying to run the same build/deploy processes on. I would like to be able to deploy the same code from a single repo to multiple systems concurrently. Thus, I have created an "overhead" pipeline, and several "processes" pipeline templates. Everything seems to be going very well, except for when I try to perform checkouts of the same repo twice in the same pipeline execution. I get the following error:
An error occurred while loading the YAML build pipeline. An item with the same key has already been added.
I would really like to be able to just click ONE button to trigger a main pipeline that calls all the templates requires and gives the parameters needed to get all my jobs done at once. I could of course define this "overhead" pipeline and then queue up as many instances as I need of it per systems that I need to deploy to, but I'm lazy, hence why I'm using pipelines!
As soon as I remove the checkout from Common.yml, the validation succeeds without any issues. If I keep the checkout in there but only call the Common.yml once for the entire Overhead pipeline, then it succeeds without any issues as well. But the problem is: I need to pull the contents of the repo to EACH of my agents that are running on completely separate environments that are in no way ever able to talk to each other (can't pull the information to one agent and have it do some sort of a "copy" to all the other agent locations.....).
Any assistance is very much welcomed, thank you!
The following is my "overhead" pipeline:
# azure-pipelines.yml
trigger:
none
parameters:
- name: vLAN
type: string
default: 851
values:
- 851
- 1105
stages:
- stage: vLAN851
condition: eq('${{ parameters.vLAN }}', '851')
pool:
name: xxxxx
demands:
- vLAN -equals 851
jobs:
- job: Common_851
steps:
- template: Procedures/Common.yml
- job: Export_851
dependsOn: Common_851
steps:
- template: Procedures/Export.yml
parameters:
Server: ABTS-01
- stage: vLAN1105
condition: eq('${{ parameters.vLAN }}', '1105')
pool:
name: xxxxx
demands:
- vLAN -equals 1105
jobs:
- job: Common_1105
steps:
- template: Procedures/Common.yml
- job: Export_1105
dependsOn: Common_1105
steps:
- template: Procedures/Export.yml
parameters:
Server: OTS-01
And here is the "Procedures/Common.yml":
steps:
- checkout: git://xxxxx/yyyyy#$(Build.SourceBranchName)

addToPath: true
architecture: 'x64'
- task: CmdLine#2
enabled: true
timeoutInMinutes: 5
displayName: Ensure Python Requirements Installed
inputs:
script: |
python -m pip install GitPython
And here is the "Procedures/Export.yml":
parameters:
- name: Server
type: string
steps:
- task: PythonScript#0
enabled: true
timeoutInMinutes: 3
displayName: xxxxx
inputs:
arguments: --name "xxxxx" --mode True --Server ${{ parameters.Server }}
scriptSource: 'filePath'
scriptPath: 'xxxxx/main.py'
I managed to make checkout work with variable branch names by using template expression variables ${{ ... }} instead of macro syntax $(...) variables.
The difference is that, template expressions are processed at compile time while macros are processed at runtime.
So in my case I have something like:
- checkout: git://xxx/yyy#${{ variables.BRANCH_NAME }}
For more information about variables syntax :
Understand variable syntax
I couldn't get it to work with expressions but I was able to get it to work using repository resources following the documentation at: https://learn.microsoft.com/en-us/azure/devops/pipelines/repos/multi-repo-checkout?view=azure-devops
resources:
repositories:
- repository: MyGitHubRepo # The name used to reference this repository in the checkout step
type: git
name: MyAzureProjectName/MyGitRepo
ref: $(Build.SourceBranch)
trigger:
- main
pool:
vmImage: 'ubuntu-latest'
#some job
steps:
- checkout: MyGitHubRepo
#some other job
steps:
- checkout: MyGitHubRepo
- script: dir $(Build.SourcesDirectory)
Could someone tell me the difference between the PUT step and the OUTPUT step in Concourse? For example, in the following type of YAML files why do we need a put step after a get? Can't we use output instead of put? If not what are the purposes of each two?
jobs:
- name: PR-Test
plan:
- get: some-git-pull-request
trigger: true
- put: some-git-pull-request
params:
context: tests
path: some-git-pull-request
status: pending
....
<- some more code to build ->
....
The purpose of a PUT step is to push to the given resource while an OUTPUT is the result of TASK step.
A task can configure outputs to produce artifacts that can then be propagated to either a put step or to another task step in the same plan.
This means that you send the resource that you are specifying on the GET step to the task as an input, to perform wherever build or scripts executions and the output of that task
is a modified resource that you can later pass to your put step or to another TASK if you don't want to use PUT.
It would also depend on the nature of the defined resource in your pipeline. I'm assuming that you have a git type resource like this:
resources:
- name: some-git-pull-request
type: git
source:
branch: ((credentials.git.branch))
uri: ((credentials.git.uri))
username: ((credentials.git.username))
password: ((credentials.git.pass))
If this is true, the GET step will pull that repo so you can use it as an input for your tasks and if you use PUT against that same resource as you are describing in your sample code, that will push changes to your repo.
Really it depends on the workflow that you want to write but to give an idea it would look something like this:
jobs:
- name: PR-Test
plan:
- get: some-git-pull-request
trigger: true
- task: test-code
config:
platform: linux
image_resource:
type: docker-image
source:
repository: yourRepo/yourImage
tag: latest
inputs:
- name: some-git-pull-request
run:
path: bash
args:
- -exc
- |
cd theNameOfYourRepo
npm install -g mocha
npm test
outputs:
- name: some-git-pull-request-output
Then you can use it on either a PUT
- put: myCloud
params:
manifest: some-git-pull-request-output/manifest.yml
path: some-git-pull-request-output
or a another task whitin the same plan
- task: build-code
config:
platform: linux
image_resource:
type: docker-image
source:
repository: yourRepo/yourImage
tag: latest
inputs:
- name: some-git-pull-request-output
run:
path: bash
args:
- -exc
- |
cd some-git-pull-request-output/
npm install
gulp build
outputs:
- name: your-code-build-output
Hope it helps!
It seems to me that drone.io does not share parameters across pipeline steps.
Is it possible to read the parameters for the plugins from a file, e.g. a directive
like "from_file" similar to the already existing "from_secret"? This is how one could use it:
kind: pipeline
name: default
steps:
- name: get_repo_name
image: alpine
commands:
- echo "hello" > .repo_name
- name: docker
image: plugins/docker
settings:
repo:
from_file: .repo_name
username:
from_secret: docker_username
password:
from_secret: docker_password
Ability to read input from a file is more the choice of the plugin author, but creating plugins is a pretty simplistic thing as most of your variables just have to be called in as PLUGIN_VARIABLE and you can then offer such things.
https://docs.drone.io/plugins/bash/
To show that some of the plugins do read from file, one such example is drone-github-comment:
steps:
- name: github-comment
image: jmccann/drone-github-comment:1.2
settings:
message_file: file_name.txt
when:
status:
- success
- failure
FWIW, looking at your example though, it would seem you are looking to pass just the repo_name? These variables are all present in a pipeline depending of course on the runner you are using, but for Docker you get all of these:
https://docs.drone.io/pipeline/environment/reference/
I am trying to built a concourse pipeline which is triggered by git, and then runs a script in that git repository.
This is what I have so far:
resources:
- name: component_structure_git
type: git
source:
branch: master
uri: git#bitbucket.org:foo/bar.git
jobs:
- name: component_structure-docker
serial: true
plan:
- aggregate:
- get: component_structure_git
trigger: true
- task: do-something
config:
platform: linux
image_resource:
type: docker-image
source: { repository: ubuntu }
inputs:
- name: component_structure_git
outputs:
- name: updated-gist
run:
path: component_structure_git/run.sh
- put: component_structure-docker
params:
build: component_structure/concourse
- name: component_structure-deploy-test
serial: true
plan:
- aggregate:
- get: component_structure-docker
passed: [component_structure-docker]
- name: component_structure-deploy-prod
serial: true
plan:
- aggregate:
- get: component_structure-docker
passed: [component_structure-docker]
When I apply this code with fly, everything is ok. When I try to run the build. it fails with the following error:
missing inputs: component_structure_git
Any idea what I am missing here?
Agree with first answer. When running things in parallel (aggregate blocks) there are a few things to consider
How many inputs do I have? I have more than one, let's run these get steps in an aggregate block
If I have two tasks, is there a dependency between the tasks that can change the outcome of a task run, eg. Do I have an output from one task that is required in the next task
I have a sequence of put statements, let's run these steps in an aggregate block
just a guess but aggregate is causing the issue. You can't have an input from something that is executing at the same time? Why do you have aggregate anyway? This is usually used for "get" to speed up the process.
