## GCP: docker machine

**GCP(Google Cloud Platform)의 Compute Engine 인스턴스에서는 가상화 컨테이너 기능을 지원하지 않는다.**

그래서 VirtualBox 같은 하이퍼바이저를 설치해도, 도커 머신의 드라이버로 만들 수 없다. (Hosted 형태의 컨테이너가 안된다는 뜻)

아무리 이미지를 바꿔도 계속 만났던 오류 메시지:

```
joonas_yoon@gce-instance:~$ docker-machine create --driver virtualbox vm00
Running pre-create checks...
Error with pre-create check: "This computer doesn't have VT-X/AMD-v enabled. Enabling it in the BIOS is mandatory"
```

진짜 계속 찾아봤는데, 전부 안됐다.

<https://github.com/docker/machine/issues/4590>

위 이슈 쓰레드에서 해결됐다는 코멘트들 다 안됐다. 인스턴스가 E2 유형이건 아니건 그냥 다 안됐다. N1 타입도 해봤고, Linux 16.04 LTS도 해보고 마켓에 있는 이미지도 해봤다.

* Create machines on Google Compute Engine - <https://docs.docker.com/machine/drivers/gce/>

드라이버를 `google`에 맞게 설정해줘서 해결했다. `key.json`은 프로젝트에서 사용하던 credentials.json 이다.

```
joonas_yoon@gce-instance:~$ export GOOGLE_APPLICATION_CREDENTIALS=$HOME/key.json
joonas_yoon@gce-instance:~$ gcloud auth login
joonas_yoon@gce-instance:~$ docker-machine create --driver google --google-project <GOOGLE_PROJECT_ID> vm01
