Overview

Salto allows you to leverage your git provider by automatically attaching a pull request to deployment records. These pull requests capture all of the planned configuration changes in Salto deployments and allow you to:

  1. Comment, discuss and get approval from colleagues about the planned configuration changes

  2. Connect your preferred CI/CD tool in order to automate validations and deployments. You can further integrate any other external tool for additional use cases, e.g. static code analysis tools.

  3. Push and deploy additional NACL edits, made out of the Salto Platform

Integrating pull requests with Salto deployments

Salto can be configured to automatically create a pull request for any deployment record targeting a certain environment.

In order to enable this behavior, you will first need to connect your environment to a git repository and branch and make sure to turn on 'Deployment protection via Salto PRs'.


​
If your environment is already connected to a git branch, deployment protection via Salto PRs can be turned on via the version control section of the environment settings screen.

  • Once ‘Require Pull Requests’ is enabled, for any new deployment reaching the ‘deployments preview’ state, Salto will automatically create a pull request capturing the deployment details.

  • The pull request will be updated automatically upon any deployment preview change occurring as a result of element selection modification, manual edits or fetch on the deployment target environment.

  • The deploy operation in Salto will be disabled in case the pull request is not mergeable according to the branch protection rules specified in the repository settings.

Using the Salto CLI for CI/CD Automation

Having a PR that captures your deployments’ information opens the door for CI/CD automated jobs that are triggered upon creation and / or changes to the PR. These automated jobs can leverage Salto’s CLI in order to automate deployment preview checks, validation runs and deployment / promotion of changes.

Setup instructions and complete CLI interface can be found here.

Injecting CI Configuration Files

In order to trigger CI jobs upon PR creation / modification, the git branches should include configuration files for the CI tool that is being used.

To Inject your CI config files into the branches created by Salto:

  1. Create a branch in the same repository in which the PRs are created and push any CI configuration files.

  2. In the version control section of the environment settings, click the 'Select Branch' button located next to 'CI/CD configuration file location'.

Deploying additional edits using Pull Requests

Users can also use the created pull request to make additional edits to the deployed elements or support a classic "Find and Replace" use case. This can be used to perform advanced editing on your files - for example, replacing a value in many files, or introducing a large amount of new elements created by some internal script.

To include external edits in your Salto deployment:

  1. Clone the git repository to some local repo

  2. Checkout the PR "after" branch

  3. Perform your edits directly on the NACL files

  4. Commit and push these edits to your remote repo

Salto will automatically detect incoming changes, and will ask the deployer to pull these commits into the deployment.

When committing additional changes to Pull Requests, avoid force-pushing your commits as that may prevent Salto from pulling these changes properly.
