SUSE Linux Enterprise Server 12/15 使用二進制安裝docker

Docker-CE in SUSE

雖然使用zypper添加源也能安裝，不過我在SLES 12sp5 上安裝時發現好多命令還需要自己手動軟連接，乾脆網上找了找文檔，再自己小改下，用二進制部署，也是可以安裝成功的，並且使用方式上沒啥區別。
注意：目前這個辦法我自己還未在生產環境上實驗。ps: 如果經過測試等一系列環境後，上了生產沒啥問題，再刪掉這句話。如果各位在使用上有啥問題，可以評論區騷擾。

避坑點：suse上的防火牆服務名字和centos7上的不太一樣，需要修改systemd的Afer部分

1. add /usr/lib/systemd/system/docker.service
