Containerization

Use a Dockerfile from rocket guide, but modified to include a custom root certificate (uncomment and copy it here!) and a json folder as well as a static folder.

• Start your Linux from this root folder using a cool windows terminal

wsl

• Pull Kaniko image into ctr (start containerd first)

sudo ctr i pull gcr.io/kaniko-project/executor:latest

• build with Kaniko and export to a local tar

sudo ctr run --net-host --rm --mount type=bind,src=$(pwd),dst=/workspace,options=rbind:rw gcr.io/kaniko-project/executor:latest kaniko-executor /kaniko/executor --dockerfile=/workspace/Dockerfile --context=/workspace --no-push --skip-tls-verify --build-arg pkg=hello-rocket --tarPath=/workspace/rust-playground-kaniko.tar --destination=localhost/rust-playground-kaniko:latest

• Import the image into containerd

sudo ctr image import rust-playground-kaniko.tar

• Create the container

sudo ctr c create --net-host localhost/rust-playground-kaniko:latest rust-playground

• Start the task

sudo ctr t start rust-playground

• Open in the browser

  • http://localhost:8080/
  • http://localhost:8080/json
  • http://localhost:8080/api/data

• Eventually split the terminal window and stop the task

sudo ctr t kill -s 9 rust-playground

• Tag the image

sudo ctr image tag localhost/rust-playground-kaniko:latest docker.io/${DHUSER}/rust-playground-kaniko:latest

• Push the image

sudo ctr images push \
    --user "${DHUSER}:${DHTOKEN}" \
    docker.io/${DHUSER}/rust-playground-kaniko:latest

• Deploy to Kubernetes (create the cluster, see my instructions for digitalocean, update the certificate email, etc...)

cd k8s
kubectl apply -f deployment.yml
kubectl rollout status deployment/rust-web -n rust

• Open in the browser your website, e.g.:
  • https://myweb.giuliohome.org/
  • https://myweb.giuliohome.org/json
  • https://myweb.giuliohome.org/api/data
