docker - Docker 命令的含义

Question

看似简单的问题，其实并不清楚这条命令的含义:

docker run -d -p 5000:5000 --restart=always --name registry \
  -v `pwd`/certs:/certs \
  -e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/domain.crt \
  -e REGISTRY_HTTP_TLS_KEY=/certs/domain.key \
  registry:2

-v pwd/certs:/certs\一点都不清楚。谁能给个解释

Answer 1

解释

`pwd` - shell command to show current path, normally you can replace with $(pwd)

所以-v pwd/certs:/certs的意思是，将当前路径的子路径certs挂载到docker容器的文件夹/certs

每行末尾有反斜杠\，用于长输入
