  1 | kubernetes-action
  2 | =============
  3 | Interacts with kubernetes clusters calling `kubectl` commands. Integrates support for **AWS EKS**.
  4 | 
  5 | ## Usage
  6 | 
  7 | ### Basic Example
  8 | 
  9 | ```yml
 10 | name: CI
 11 | 
 12 | on:
 13 |   - push
 14 | 
 15 | jobs:
 16 |   deploy:
 17 |     runs-on: ubuntu-latest
 18 |     steps:
 19 |       - uses: actions/checkout@v2
 20 | 
 21 |       - name: Trigger deploy
 22 |         uses: Consensys/kubernetes-action@master
 23 |         env:
 24 |           KUBE_CONFIG_DATA: ${{ secrets.KUBE_CONFIG_DATA }}
 25 |         with:
 26 |           args: apply deployment.yaml
 27 | ```
 28 | 
 29 | ### EKS Example
 30 | ```yml
 31 | name: CI
 32 | 
 33 | on:
 34 |   - push
 35 | 
 36 | jobs:
 37 |   deploy:
 38 |     runs-on: ubuntu-latest
 39 |     steps:
 40 |       - uses: actions/checkout@v2
 41 | 
 42 |       - name: Configure AWS Credentials
 43 |         uses: aws-actions/configure-aws-credentials@v1
 44 |         with:
 45 |           aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
 46 |           aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
 47 |           aws-region: us-east-1
 48 | 
 49 |       - name: Trigger deploy
 50 |         uses: Consensys/kubernetes-action@master
 51 |         env:
 52 |           KUBE_CONFIG_DATA: ${{ secrets.KUBE_CONFIG_DATA }}
 53 |         with:
 54 |           args: apply deployment.yaml
 55 | ```
 56 | 
 57 | ## Config
 58 | 
 59 | ### Secrets
 60 | 
 61 | One or more **secrets** needs to be created to store cluster credentials. (see [here](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/creating-and-using-encrypted-secrets) for help on creating secrets). 
 62 | 
 63 | #### Basic
 64 | - **KUBE_CONFIG_DATA**: A `base64` representation of `~/.kube/config` file.
 65 | 
 66 | ##### Example
 67 | ```bash
 68 | cat ~/.kube/config | base64 | pbcopy # pbcopy will copy the secret to the clipboard (Mac OSX only)
 69 | ```
 70 | 
 71 | #### EKS
 72 | - **KUBE_CONFIG_DATA**: Same as Basic configuration above.
 73 | 
 74 | - **AWS_ACCESS_KEY_ID**: AWS_ACCESS_KEY_ID of a IAM user with permissions to access the cluster.
 75 | 
 76 | - **AWS_SECRET_ACCESS_KEY**: AWS_SECRET_ACCESS_KEY of a IAM user with permissions to access the cluster.
 77 | 
 78 | Make sure your users has the proper IAM permissions to access your cluster and that its configured inside kubernetes (more info [here](https://docs.aws.amazon.com/eks/latest/userguide/add-user-role.html)).
 79 | 
 80 | ## Outputs
 81 | 
 82 | - **result**: Output of the `kubectl` command.
 83 | 
 84 | ### Example
 85 | ```yaml
 86 |       - name: Save container image
 87 |         id: image-save
 88 |         uses: Consensys/kubernetes-action@master
 89 |         env:
 90 |           KUBE_CONFIG_DATA: ${{ secrets.KUBE_CONFIG_DATA }}
 91 |         with:
 92 |           args: get deploy foo -o jsonpath="{..image}"
 93 | 
 94 |       - name: Print image
 95 |         run: 
 96 |           echo ${{ steps.image-save.outputs.result }}
 97 | ```
 98 |
