DevPill 2: How to build and push a docker image to google cloud Artifact Registry

#gcp #docker #containers

1. Specify Dockerfile.

Example:

FROM golang:1.25 AS builder
WORKDIR /app
COPY . .
WORKDIR /app/services/api-gateway/cmd
RUN CGO_ENABLED=0 GOOS=linux go build -o api-gateway

FROM alpine:latest
RUN apk --no-cache add ca-certificates
WORKDIR /root/
COPY --from=builder /app/services/api-gateway/cmd/api-gateway .
CMD ["./api-gateway"]
Enter fullscreen mode Exit fullscreen mode

2. Docker "build" to create the image locally. Example: 

docker build -t us-central1-docker.pkg.dev/<project-id>/<repository-name>/api-gateway:latest --platform linux/amd64 -f infra/production/docker/api-gateway.Dockerfile .
Enter fullscreen mode Exit fullscreen mode

3. Push image to Google Cloud Artifact Registry: 

docker push us-central1-docker.pkg.dev/<project-id>/<repository-name>/api-gateway:latest
Enter fullscreen mode Exit fullscreen mode

Now your image will be available to any GCP service you would like to use.
