Docker

We'll be using Docker to deploy Notely to Google Cloud Run. If you're not familiar with Docker, you should take our Learn Docker course here first.

Make sure you have Docker installed by running docker --version in your terminal. You should be on at least version 20.10.21.

Assignment

Run the scripts/buildprod.sh script found in the root of the Notely repository. This will produce a notely binary that's compiled for Linux, which is the OS our Docker image will run on.

./scripts/buildprod.sh

docker build -t DOCKERHUB_NAMESPACE/notely:latest .

DOCKERHUB_NAMESPACE should be replaced with your Docker Hub username.

docker run -e PORT=8080 -p 8080:8080 DOCKERHUB_NAMESPACE/notely:latest

Open the app in your browser at http://localhost:8080. You should see the Notely app running locally!

Run and submit the CLI tests.

If you get an architecture or exec format error, that's probably because your machine is different than the intended Docker Container.

macOS

Set GOOS to linux and GOARCH to arm64 in the build script or set them when building the binary

GOOS=linux GOARCH=arm64 go build -o notely .

Set the --platform flag to linux/arm64 in the Dockerfile or when running the docker build command.

docker build -t DOCKERHUB_NAMESPACE/notely:latest . --platform=linux/arm64

Use http, not https!

Creating a user on the Notely site is not expected to work yet, we haven't set up the database!
