From root dir of app
Run: docker-compose up
Run detached: docker-compose up -d
Rebuild container: docker-compose up --build
Bring down container: docker-compose down
Stop running process and clear volumes: docker-compose down --remove-orphans --volumes
Get IP address of docker container: docker inspect <container_id> | grep IPAddress -> hostname
Remove dangling images: docker system prune
Remove all unused images: docker system prune -a
Remove all unused images and volumes: docker system prune -a --volumes
from root dir, run docker-compose -f docker-compose.test.yml up --build --abort-on-container-exit
When the environment is running, go to localhost:8080/swagger/index.html

Minikube (Kubernetes) Deployment
spin up: minikube start
spin down: minikube stop
set env vars on the cluster: kubectl create -f mysql-secret.yaml
check secrets were created: kubectl get secrets
check secret elements: kubectl describe secrets mysql-secret
Deploying DB to Kubernetes
Order: pv, pvc, deployment, service
kubectl apply -f mysql-db-pv.yaml
kubectl apply -f mysql-db-pvc.yaml
kubectl apply -f mysql-db-deployment.yaml
kubectl apply -f mysql-db-service.yaml
view pod after service is spun up: kubectl get pods
check logs if there's an error:
kubectl describe pod <pod_name>
kubectl logs <pod_name>
kubectl logs <pod-name> -c <container-name>
container-name comes from describe command
Build image for kubernetes: docker build -t go-blog-kubernetes .
Tag image to repo on dockerhub: docker tag <image-name> <dockerhub-username>/<repository-name>:<tag-name>
ie. docker tag go-blog-kubernetes dmdinh/go-blog:X.X.X
Deploying API to Kubernetes
Create and apply kubernetes from the yaml files:
kubectl apply -f api-mysql-deployment.yaml
kubectl apply -f api-mysql-service.yaml
Check pod status: kubectl get pods
Get services in cluster: kubectl get services
Get url exposed: minikube service <service-name> --url (minikube service go-blog-mysql --url)
