Use case
You would like different branches to deploy to different locations, or otherwise use different keys depending on the branch.
Solution:
In this article, we will provide an example of using conditionals for the purposes of selecting the appropriate AWS key.
Please see the following example, which will set the AWS_ACCESS_KEY_ID variable based on whether the branch is master or a dev branch.
Note that both MASTER_AWS_ACCESS_KEY_ID and DEV_AWS_ACCESS_KEY_ID are set as protected variables in this pipeline.
```version: '1.0'
steps: exportmastercreds: image: alpine:latest commands: - cfexport AWSACCESSKEYID=$MASTERAWSACCESSKEYID > /dev/null when: branch: only: - master
exportdevcreds: image: alpine:latest commands: - cfexport AWSACCESSKEYID=$DEVAWSACCESSKEYID > /dev/null when: branch: only: - /dev-.*/i
awsclistep: image: etc //provide the remainder of your deploy step here ```
Notes
You can also make use of a single freestyle step to perform this. We would suggest using a shell script to compare ${{CF_BRANCH}} according to your use case.
We suggest looking into Branch Protection from your Git provider if this is being done for access control.
