Minikube 및 testContainer(Docker이용한 테스트) 세팅 feat_Docker Desktop 유료화

DockerDesktop의 유료화로 인한 대체제로 minikube를 사용하라는 말이 들린다. 

minikube는 로컬환경에서 kubernetes 클러스터를 실행하는 데 사용된다고 한다

그러나 컨테이너를 실행하는 데 사용할 수 있는 도커 데몬도 실행되기에 기존의 Docker Desktop을 대체할 수 있다고 한다.

 

# Install hyperkit and minikube
brew install hyperkit
brew install minikube

# Install Docker CLI
brew install docker
brew install docker-compose

# Start minikube
minikube start

# Tell Docker CLI to talk to minikube's VM
eval $(minikube docker-env)

# Save IP to a hostname
echo "`minikube ip` docker.local" | sudo tee -a /etc/hosts > /dev/null

# Test
docker run hello-world

위와 같이 미니큐브 설치 및 docker-cli가 제대로 동작하는것을 확인하고, 이제 Java테스트용 라이브러리인 

 

testContainer를 돌리면 되겠거니 하여 코드를 돌리니 에러가 떨어진다.. ㅠ

아무리 찾아보아도 해답을 찾을수 없어 StackOverflow에 물어보기로 하였다.

How can i use testcontainer in mac os with out Docker Desktop?

 

답변이 하루인가 이틀만에 달렸는데, 다음의 명령어를 수행하라고 한다.

$ eval $(minikube -p minikube docker-env)
$ echo "docker.host=$DOCKER_HOST" >> ~/.testcontainers.properties
$ echo "docker.cert.path=$DOCKER_CERT_PATH" >> ~/.testcontainers.properties
$ echo "docker.tls.verify=true" >> ~/.testcontainers.properties

이렇게 하고 testContainer를 수행하니까 아래와 같은 결과가 나왔다.

너무 잘되어서 따봉 과 답변체크를 눌러주고 이슈를 완료처리 하였다.

 

정말 행복하다
