GCP

SSH to your VM

https://ithelp.ithome.com.tw/articles/10251134

  1. generate a new ssh key or use existing ssh key and paste (the public one) to your Computing Engine VM (click the VM name → edit → add ssh key → save)
  2. ssh -i [private_key_location] id_ed25519 [username]@[external_IP_of_VM]
    • if successfully go into your VM, go to next step
    • if permission denied, then the public key on the VM and your private key on your machine don't match

to set alias, go to ~/.ssh/config and add 

Host [my_alias]
HostName   [external_ip]
Port 22
IdentitiesOnly yes
IdentityFile [private key location]
User [username]

change the []to fit your need

and then just simply ssh my_alias to ssh into it

Cloud Run

GCP's serverless solution

Follow this guide to deploy you full stack app with a docker image.

Basically, with your Dockerfile ready, GCP/Firebase project set up, and google cloud CLI installed, do these to deploy

cicd: ci cd
ci:
    gcloud builds submit --tag gcr.io/<project_name>/<image_name>
cd:
    gcloud run deploy --image gcr.io/<project_name>/<image_name>

Now it will be deployed to a very ugly domain. You can route Firebase's static site domain to your cloud run app, as they're much cleaner. See the section below.

Env

Just edit the env in the web UI, and then use the usual way to get the env in your language.

See https://cloud.google.com/run/docs/configuring/environment-variables

Route Firebase domain to Cloud Run App

Download firebase CLI, firebase init, and the change edit firebase.json

firebase.json

{
  "hosting": {
    "rewrites": [
      {
        "source": "**",
        "run": {
          "serviceId": "<project_name>",
          "region": "<region>"
        }
      }
    ]
  }
}

Now your app will also be available on

  • <project_name>.web.app/
  • <project_name>.firebaseapp.com/

Github Action

https://github.com/google-github-actions/setup-gcloud

Auth

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - id: 'auth'
        uses: 'google-github-actions/auth@v0'
        with:
          credentials_json: ${{ secrets.GCP_CREDENTIALS }}

      - name: GCP auth
        run: gcloud auth configure-docker

And then you can gcloud commands freely

Troubleshooting

The user-provided container failed to start and listen on the port defined provided by the PORT=8080 environment variable.

  1. Make sure your app runs on 0.0.0.0 (127.0.0.1 is not ok)
  2. Make sure the port is 8080
