Manage An AWS EC2 Instance

In the following guide, you are going to create self-service actions in Port that execute a GitHub workflow to manage an EC2 instance in the following ways:

1. Terminate an Instance
2. Reboot an instance
3. Resize an Autoscaling Group

Prerequisites

1. Install Port's GitHub app by clicking here.
2. Use the Port AWS exporter to ingest AWS EC2 instances and autoscaling groups into Port to create the blueprints and entities.

tip

Using the Port AWS exporter The Port AWS exporter supports ingesting different AWS resource types. For the sake of this guide, you may run the following command in the installation step to only ingest relevant resources:

terraform apply -var 'resources=["ec2_instance", "autoscaling_group"]'

3. Create the following GitHub Action secrets: _ Port credentials: _ PORT_CLIENT_ID - Port Client ID learn more * PORT_CLIENT_SECRET - Port Client Secret learn more

   • AWS Cloud credentials:
     • AWS_ACCESS_KEY_ID: Your AWS access key.
     • AWS_SECRET_ACCESS_KEY: Your AWS secret access key.
     • AWS_REGION - the aws region which contains your ec2 instances.

Terminating an Instance

1. Create the Port action on the ec2Instance blueprint: - Head to the self-service page. - Click on the + New Action button. - Click on the {...} Edit JSON button. - Copy and paste the following JSON configuration into the editor:

Port Action: Terminate EC2 Instance

tip

• <GITHUB-ORG> - your GitHub organization or user name.
• <GITHUB-REPO-NAME> - your GitHub repository name.

{
  "identifier": "terminate_ec2_instance",
  "title": "Terminate Instance",
  "description": "Terminate an EC2 Instance",
  "trigger": {
    "type": "self-service",
    "operation": "DELETE",
    "userInputs": {
      "properties": {},
      "required": []
    },
    "blueprintIdentifier": "ec2Instance"
  },
  "invocationMethod": {
    "type": "GITHUB",
    "org": "<GITHUB-ORG>",
    "repo": "<GITHUB-REPO-NAME>",
    "workflow": "terminate-instance.yml",
    "workflowInputs": {
      "port_context": {
        "entity": "{{ .entity }}",
        "blueprint": "{{ .action.blueprint }}",
        "runId": "{{ .run.id }}",
        "trigger": "{{ .trigger }}"
      }
    },
    "reportWorkflowStatus": true
  },
  "requiredApproval": false,
  "publish": true
}

2. Create a workflow file under .github/workflows/terminate-instance.yaml with the following content:

GitHub workflow script

terminate-instance.yaml

name: Terminate EC2 Instance

on:
  workflow_dispatch: # Trigger this workflow manually
    inputs:
      port_context:
        required: true
        description: 'Action and general context (blueprint, run id, etc...)'
        type: string

jobs:
  terminate-instance:
    runs-on: ubuntu-latest
    steps:
      - name: Create a log message
        uses: port-labs/port-github-action@v1
        with:
          clientId: ${{ secrets.PORT_CLIENT_ID }}
          clientSecret: ${{ secrets.PORT_CLIENT_SECRET }}
          baseUrl: https://api.getport.io
          operation: PATCH_RUN
          runId: ${{fromJson(inputs.port_context).runId}}
          logMessage: Configuring AWS credentials and terminating EC2 instance with ID ${{ fromJson(inputs.port_context).entity.identifier }}

      - name: Configure AWS credentials
        uses: aws-actions/configure-aws-credentials@v1
        with:
          aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
          aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
          aws-region: ${{ secrets.AWS_REGION }}

      - name: Terminate EC2 instance
        run: aws ec2 terminate-instances --instance-ids ${{ fromJson(inputs.port_context).entity.identifier }}

      - name: Create a log message
        uses: port-labs/port-github-action@v1
        with:
          clientId: ${{ secrets.PORT_CLIENT_ID }}
          clientSecret: ${{ secrets.PORT_CLIENT_SECRET }}
          baseUrl: https://api.getport.io
          operation: PATCH_RUN
          status: 'SUCCESS'
          runId: ${{fromJson(inputs.port_context).runId}}
          logMessage: EC2 instance with ID ${{ fromJson(inputs.port_context).entity.identifier }} terminated successfully

3. Trigger the action from Port's self-service page or from the context menu of an EC2 entity.

Rebooting an Instance

1. Create the Port action on the ec2Instance blueprint: - Head to the self-service page. - Click on the + New Action button. - Click on the {...} Edit JSON button. - Copy and paste the following JSON configuration into the editor:
