Docker-CE in SUSE

虽然使用zypper添加源也能安装，不过我在SLES 12sp5 上安装时发现好多命令还需要自己手动软连接，干脆网上找了找文档，再自己小改下，用二进制部署，也是可以安装成功的，并且使用方式上没啥区别。

避坑点：suse上的防火墙服务名字和centos7上的不太一样，需要修改systemd的After部分

Download

wget https://download.docker.com/linux/static/stable/x86_64/docker-19.03.15.tgz

Install

Add group for docker

tar -zxvf docker-19.03.15.tgz

Config Containerd

• create /etc/containerd/config.toml

mkdir -p /etc/containerd

cat > /etc/containerd/config.toml <

mkdir -p /etc/docker

cat > /etc/docker/daemon.json <

systemctl daemon-reload
systemctl enable docker.service --now
