0. 개요 (컴퓨터 스펙)

• OS: Ubuntu 24.04 LTS

1. Step-by-step

1. Docker Engine install ( Add Docker's official GPG key:)

sudo apt-get update
sudo apt-get install apt-transport-https 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

2. apt sources에 repository 추가

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

3. 패키지 DB 업데이트

sudo apt-get update

4. Docker 설치

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

5. 실행

sudo docker run hello-world

2. 이슈 건

• E: Malformed entry 1 in list file /etc/apt/sources.list.d/archive_uri-https_download_docker_com_linux_ubuntu_jammy-jammy.list (Component) 와 같은 오류 조치
• apt 추가시 이슈가 된 것이고, /etc/apt/sources.list.d/docker.list파일 편집 필요

sudo vi /etc/apt/sources.list.d/docker.list

# 파일 내에 https://download.docker.com/linux/ubuntu 띄고 ~~ stable
# Ex) deb [arch=amd64] https://download.docker.com/linux/ubuntu noble stable
