执行以下步骤对私人证书进行docker注册：

1. 使用以下命令生成私有SSL证书。这将创建certs文件夹与两个文件domain.crt，domain.key
   
   

    
    openssl req -newkey rsa：4096 -nodes -sha256 -keyout certs / domain。 key -x509 -days 365 -out certs / domain.crt 
   



2. 使用以下命令启动docker注册表：
   
   

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




3. 在另一台要拉出图像的机器上，将

    certs / domain.crt 

   文件复制到

    / etc /docker/certs.d/<<DockerRegistryServerHostname>>：< DockerRegistryPort>> /ca.crt 

   确保证书文件的名称是ca.crt（不是域）。 crt）。

   
   
   

   例如，如果docker注册表IP地址是docker.registry，并且端口是5000，那么文件夹名称将是

    / etc / docker / ce rts.d / porter.registry：5000 / 




4. 现在运行docker pull命令。你不应该面对任何问题。

I configured insecure registry by self singed certificate.After providing user name and password , getting error message as " Error response from daemon: Get https://ip address:5000/v1/users/: x509: certificate signed by unknown authority".

Execute following steps to docker registry with private certificates:

1. Generate private SSL Certificate with following command. This will create certs folder with two file domain.crt, domain.key

   openssl req -newkey rsa:4096 -nodes -sha256 -keyout certs/domain.key  -x509 -days 365 -out certs/domain.crt
   

2. Start docker registry with following command:

   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
   

3. On another machine where you want to pull the images, copy

   certs/domain.crt

   file to

   /etc/docker/certs.d/<<DockerRegistryServerHostname>>:<<DockerRegistryPort>>/ca.crt

   Make sure the name of certificate file is ca.crt (not domain.crt).

   For example, if docker registry IP address is docker.registry and port is 5000 then folder name will be

   /etc/docker/certs.d/docker.registry:5000/

4. Now run docker pull command. You should not face any issue.
