在Ubuntu或Debian上创建Docker环境

■ 安装所需的库

apt install -y \
  apt-transport-https \
  ca-certificates \
  curl \
  software-properties-common
# Debianのイメージにもよると思いますが、debianは下記も必要でした
apt install -y \
    gnupg

■Ubuntu

■乌班图 (wū tú)

DOCKER_COMPOSE_VERSION=1.28.5

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | apt-key add - \
  && curl -L "https://github.com/docker/compose/releases/download/${DOCKER_COMPOSE_VERSION}/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose \
  && chmod +x /usr/local/bin/docker-compose \
  && add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" \
  && apt update -y \
  && apt install -y \
    docker-ce

■Debian

# docker-composeは入れていません
curl -fsSL https://download.docker.com/linux/debian/gpg | apt-key add  - \
    && add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/debian $(lsb_release -cs) stable" \
    && apt update \
    && apt install -y \
        docker-ce
