고구마's 문제 해결 Note

• Docker 홈페이지에 너무 쉽게 잘 설명되어 있음
  • Proxy Server 뒤에서 설정하는 경우 제외하곤 매우 간단
  • https://docs.docker.com/engine/install/ubuntu/

• Apt repository 추가

# Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

# Add the repository to Apt sources:
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update

•  설치

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

• 확인

sudo docker run hello-world

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

• 추가 정보
  • docker 설치 시 docker-compose가 같이 설치되는데 docker-compose 명령어는 /usr/libexec/docker/cli-plugins/docker-compose 라는 요상한 곳에 설치가 됨
  • 해당 path를 $PATH에 추가해도 좋겠지만...
  • 난 그냥 /usr/local/bin 에 심볼릭 링크 추가함
