How to use Docker to deploy an image to Google Cloud Platform

gcp_deploy.md

Setup Google Cloud Platform (GCP)

• Login to https://console.cloud.google.com/
• Create a project (take note of project's ID)
• Enable billing
• Go to https://console.cloud.google.com/compute/instances
• Create a VM instance
  • Name: use a semantic name (take note of instance's name)
  • Region and zone: most local
  • Machine type: smallest possible f1-micro
  • (Optional) Tick "Deploy a container image to this VM instance" and enter the Docker image name
  • Boot disk: Choose Debian/Linux or Container-Optimized OS
  • Create & wait (take note of instance's external IP)
• Go to https://console.cloud.google.com/compute/metadata/sshKeys
• Add local ~/.ssh/id_rsa.pub content for project-wide ssh access
• Make sure ssh with external IP works
• Enable project's Container Registry API

Build and deploy Docker image

• Add Dockerfile
• docker build . -t {image_name} (gcr.io/{project_id}/{instance_name}:{image_tag}) (e.g. gcr.io/phattv-ecommerce/phattv-ecommerce-backend:1.0.0 or docker build . -t gcr.io/evisa-198403/evisa:3.1.1)
• (optional) docker run --name {container_name} --rm -d -p 80:80 {image_name}
• gcloud auth login & choose your account
• docker -- push {image_name}

Apply Docker image on vm instance without Kubenetes (k8s)

• ssh with external IP
• docker images
• docker run --name {container_name} --rm -d -p 80:80 {image_name}

Apply Docker image on vm instance with Kubenetes (k8s)
