TeamCity deploy previous build - github

Is it possible for TeamCity deploy config to deploy build version before most recent ?
My source code is on GitHub and I have a TC pipeline consisting of a build config and a deploy config.
On creation of PR, that branch is built ( but not deployed ).
On merge PR to master, master branch is built.
Deploy config only deploys builds of master branch and is triggered by successful build of master branch.
For troubleshooting purposes, I'd like to deploy a previous master build.
Is this possible ?

It really depends on how your build is setup. If the deploy config content is also in source control, then you can try tagging the master branch revision you want and giving teamcity that tag as your branch input to build when you trigger the deploy build. If you have a snapshot dependency on that deploy build, then it will queue the build it depends on with the same branch input parameter except it finds a suitable build (if you configure it to use a suitable build).

Merge GitHub branches from Azure

I am setting up CI/CD at work and there is one step I’m not sure how to do and furthermore, if it is a right thing do.
For background, I am used to develop in C# with Visual Studio, source code in TFS and deploying with basic script that copies files on the intranet.
Now, I’m requested to setup Build and Release pipelines on Dot Net Core projects in GitHub.
I have three branches on this project: DEV, RELEASE and MASTER
I created one pipeline that triggers on DEV’s commits, creates an artefact and deploy to DEV server.
Those are the pipelines that deploy all developers work to a DEV server where they run their own tests.
Next step, when we want to deploy to staging servers, we click a button in Azure, this merge the DEV branch to the RELEASE branch but I know close to nothing in GitHub, not even sure those are the appropriate words.
When the merge is done, this will trigger a build pipeline that will create a different artefact, when this artefact is updated, deploy to staging server.
Once this release is validated on Staging and Quality, we would merge RELEASE to MASTER and do the same until PROD servers. It is all on intranet and self-hosted agents.
Is that a good way of doing things? Can it be done this way? I need a PowerShell task or is there something that exists?
If you are using Azure DevOps pipeline, the pipeline should select GitHub for repository type, then we can configure the CI trigger.
a. Configure CI trigger:
Classic steps:
1.Open project setting->Service connections->select GitHub-> create a new GitHub service connection
2.Create a new build pipeline via classic editor-> Select GitHub as the source.
3.Open pipeline->select the tab Triggers-> enable the option Enable continuous integration and configure the Branch filters
b.YAML steps:
1.Open project setting->Service connections->select GitHub-> create a new GitHub service connection
2.Create a new build pipeline and select GitHub(YAML)
c.The sample of Check out GitHub repositories in your pipeline
resources:
repositories:
- repository: MyGitHubRepo # The name used to reference this repository in the checkout step
type: github
endpoint: MyGitHubServiceConnection
name: MyGitHubOrgOrUser/MyGitHubRepo
trigger:
- {branch name}
Configure CD trigger:
Please refer to this doc to configure the release trigger.
If you are using GitHub action.
Please select the correct workflow to configure the CI/CD, Please refer this doc for more details
CI sample:
on:
push:
branches:
- ' DEV'
Update1
When Dev branch is updated, it is built and deployed to Dev server by pipeline.
Create build A and release B, configure the CI build trigger, when the branch Dev is updated, it triggers the build pipeline A, and when build pipeline A is completed, it triggers the release pipeline B.
click a button to synchronize Dev branch to Release branch.
We cannot see the button, as a workaround, we can add task powershell and call the API to create pull request and complete the pull request. We also can add task cmd and publish the code via git cmd

Selecting correct build artifacts for pull request release combining 4 different builds artifacts

So I have a application split in 4 different repositories which all have their own Azure Pipeline build. But the artifacts of these 4 builds are deployed in one release (into one application).
On a check-in (pull request merge) on our development branch in one of the repos, a build for that repo is started. When this build completes, a release is triggered with the newly finished build artifact + 3 older artifacts based on the "Latest from the build pipeline default branch with tags" from the other repos. So always the latest builds from the development (dev) branch.
Now we want to also deploy an environment for every pull request that is created in the different repos, so our business can test a pull request.
I have the release pipeline done (the actual deploying of the environment), but not sure how to select the artifacts correctly. After a build on a pull request branch, I need to start a release with the pull request artifacts from that triggering build + the latest dev branch artifacts from the other 3 builds.
Manually I can start a new release, by default it selects all the dev artifacts, but by hand I can select the correct artifacts for the PR branch and start a correct deployment. But I want to automate (trigger) this.
How can I configure this automated trigger? Could I use tags? Or am I thinking about this in a wrong way?
Edit
I ended up setting this up by using 4 different stages which have different artifact filters. A stage for each artifact. For that artifact we allow dev_* and all other artifacts need to be from dev_. That way the correct stage is triggered for each artifact trigger, selecting the feature branch and dev branch for others.
It is not the ideal solution, because it does require some duplication of code, but by using Task Groups I have been able to minimize this. But for now I don't see a better solution.

Using a variable for branch name is not working

We have one build pipeline (Product1) that use multiple branches (dev, test, prod).
In release pipeline/artifacts settings, we use the following settings:
Default version: Latest from a specific branch with tags
Branch: $(Branch.name) --> this is settable at release time.
The scenario that we are having:
The latest successful build is using the dev branch.
There is another successful build using the test branch.
Create new release, and set Branch.name to test --> it does not use test branch, it uses the last successful one which is dev branch.
How can we use branch variables in release pipelines?
As you set the Default version: Latest from a specific branch with tags.
You need to add tags for builds, then specify the specific tag in artifacts settings, otherwise it will use the last successful builds generated from the build pipeline (will ignore the specified branch).
For example, in below screenshot I added a tag master for the successful build using the master branch, then specify the tag in Artifact settings. Thus when you create a release it will automatically select the latest build which has the tag master and using master branch.

Add TFS Build status to github

I've user Azure portal to setup continuous integration for my Web App. Sources are hosted on GitHub.
When I click GitHub project->Code->Branches, I see build status for master branch:
All very nice untill now. However, I've manually setup CI build on dev branch in VSTS, but it is not shown in github.
How do I report build status back to github, so I will see it on dev branch as well?
From the piture you posted above, you have pushed 7 commits for master branch, no commits for dev branch. Now you set up a CI build in VSTS to build your project in dev branch. Make sure that Trigger path has set to dev branch correctly in your build definition. Then you push a commit for dev branch, this build definition will be triggered and you will see the build symbol in GitHub.
In addition, the symbol appears only for CI build, if you manually trigger the build VSTS, it doesn't show.

Jenkins - Promoting a build to different environments

I was hoping for some guidance on the best way to promote a build through its environments.
We have 3 environments, DEV, STAGING, PROD.
The DEV Jenkins build is running in a continuous integration set-up, as code is checked in to subversion, Jenkins will run a new build (clean, compile, test, deploy).
The tricky bit is when it comes to STAGING and PROD.
The idea was to be able to manually promote a successful DEV build to STAGING.
STAGING build would check out the DEV's SVN Revision number, build, test, deploy to staging and finally create a branch in SVN.
Lastly the release manager could manually promote the STAGING build to PROD.
PROD build would check out the branch from the previous STAGING build, deploy to PROD and tag the branch as a release.
I have tried to use a combination of the Promotion Builds Plugin and the Paramterized Trigger Plugin but with no luck. The Subversion Revision number doesn't seem to get passed between DEV build to STAGING build.
Does anyone have any guidance on their process to promote a build through multiple environments?
Another approach is to make use of the Artifact storage Jenkins provides coupled with the Copy Artifact Plugin.
When a build is completed, you could instruct Jenkins to persist your application, either as a compressed zip/tar.gz or as an application bundle (jar/war)
Trigger a downstream job and use the Copy Artifact to retrieve the recorded artifact from the upstream job (or use parameterised builds)
Deploy/Unzip artifact as necessary - Build shell script/maven deploy?
Retest application using the same sources/binaries as was created in step 1
Repeat for PROD as necessary
This approach would allow you to fingerprint the artifacts, and thus Jenkins would link builds together in the UI, as well as allow more formal sign off.
In this scenario, why do you need to go back and label the branch in svn? We don't use svn, but w/ TFS, when Hudson/Jenkins gets the code, the changeset number it has retrieved is in the build log. So we know what code the build came from, and could get back to it at any time.
Then we promote the build from environment to environment using Hudson, the source control system doesn't need to know where the code is deployed.
If it's absolutely necessary to store the SVN Revision ID, then add a build step to your DEV job that copies it to a file. Something like this:
echo %SVN_REVISION%>revision.ini
or something like this:
echo MY_SVN_REVISION=%SVN_REVISION%>revision.ini
Then artifact revision.ini. When doing a STAGING build, use the Copy Artifact plugin (as mentioned by a previous user) to retrieve the revision.ini file specific to the build and load it into a variable. Then use that variable in a command line call to "svn" to build the tag.
