[Linux] Ubuntu에서 Docker 설치하기

Uninstall old versions (이전 버전 제거하기)

 $ sudo apt-get remove docker docker-engine docker.io containerd runc

 

Install using the apt repository

1. Update the apt package index and install packages to allow apt to use a repository over HTTPS:

 $ sudo apt-get update
 $ sudo apt-get install \
    ca-certificates \
    curl \
    gnupg

2. Add Docker’s official GPG key:

$ sudo mkdir -m 0755 -p /etc/apt/keyrings
$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

3. Use the following command to set up the repository:

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