sh CoreOS-Dokcer使用Docker加速器，安装Docker Compose

Posted 2021-05-07

#!/bin/sh
# 如何使用Docker加速器
# 针对Docker客户端版本大于1.10的用户

# 您可以通过修改daemon配置文件/etc/docker/daemon.json来使用加速器：
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://gpkywf9i.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

# Install Docker Compose as a container
sudo mkdir -p /opt/bin
# curl -L --fail https://github.com/docker/compose/releases/download/1.13.0/run.sh > /opt/bin/docker-compose
sudo tee /opt/bin/docker-compose <<-'EOF'
#!/bin/sh
#
# Run docker-compose in a container
#
# This script will attempt to mirror the host paths by using volumes for the
# following paths:
#   * $(pwd)
#   * $(dirname $COMPOSE_FILE) if it's set
#   * $HOME if it's set
#
# You can add additional volumes (or any docker run options) using
# the $COMPOSE_OPTIONS environment variable.
#
