解決Got permission denied while trying to connect to the Docker daemon socket

jonesyeh docker、ubuntu

安裝docker之後，每次執行docker時若沒有使用sudo都會顯示Got permission denied while trying to connect to the Docker daemon socket 錯誤訊息，只要執行底下步驟就可以解決此問題

1.建立並確認是否存在docker群組，若有存在就會出現已經存在docker群組訊息

sudo groupadd docker

2.將帳號加入到docker群組

sudo gpasswd –a $USER docker

3.group 的資訊並不會立刻更新，為了要能立刻產生作用，執行 newgrp docker

4.重新啟動docker服務

sudo systemctl restart docker
