The Krane Github Action to continuously deploy changes
Typically in your pipelines you'll have a build image step and a push image step. The last step deploying your changes to a target environment or machine. Below is an example setting up the Krane Github Action.
on:
push:
branches:
- main
jobs:
deploy-to-krane:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
- uses: krane/action@master
with:
endpoint: https://krane.example.com
token: ${{ secrets.KRANE_TOKEN }}
file: ./deployment.json
tag: latest| Input | Description | Required |
|---|---|---|
| endpoint | Endpoint to the Krane instance, for example https://krane.example.com | true |
| token | Token used for authenticated Krane requests | true |
| file | Path to Krane deployment config | true |
| tag | Image tag to use when triggering new deployment | false (default latest) |
The following builds and publishes and image to Docker then triggers a deployment with Krane.
