How to run with docker-compose

• You can run this application on your local with docker-compose.
• Note: Running on local cannot prepare SSL configuration, so you cannot set localhost to linebot's callback method. You can just check how this app works.

$ pwd
/path/to/dir/linebot/
# Build & Run containers
$ docker-compose up
# Stop & Delete containers
$ docker-compose down --rmi all --volumes --remove-orphans

How to run on GKE

# Create your artifacts repositories on GCP.
$ gcloud artifacts repositories create linebot-repo \
    --project=gcp-compute-engine-343613 \
    --repository-format=docker \
    --location=asia-northeast1 \
    --description="Docker repository"

# Create your own cluster.
$ gcloud container clusters create linebot-gke --num-nodes 3 --zone asia-northeast1

# Build image and deploy
$ pwd
/path/to/dir/linebot/
# Flask App image build and push
$ gcloud builds submit \
    --tag asia-northeast1-docker.pkg.dev/gcp-compute-engine-343613/linebot-repo/app-server:1.0.0 ./app/
# Nginx container image build and push
$ gcloud builds submit \
    --tag asia-northeast1-docker.pkg.dev/gcp-compute-engine-343613/linebot-repo/linebot-nginx:1.0.0 ./web/

# Apply each k8s objects
# Build & Run containers
kubectl apply \
    -f app/deployment.yaml \
    -f app/service.yaml \
    -f web/deployment.yaml \
    -f web/service.yaml  \
    -f db/deployment.yaml  \
    -f db/service.yaml  \
    -f db/secret.yaml  \
    -f db/configmap.yaml \
    -f db/persistent-volume.yaml \
    -f ingress/managed-cert.yaml \
    -f ingress/managed-cert-ingress.yaml

Other things you have to do for SSL configration

• Prepare your own domain(like Google Domain)
• Reserving a static external IP address link
• DNS (DNS A record) setting to connect static external IP address with your domain.

When you are enough to run..

# Make sure delete cluster not to be billed!
$ gcloud container clusters delete linebot-gke --zone asia-northeast1-a
