Docker pull on mac reports an error Error response from daemon: Get https://xx.xx.xx.xx/v2/: Service Unavailable

error¶

Execute docker pull xx.xx.xx.xx/xx/xx, and the following error is reported when downloading the image of the private library:

Error response from daemon: Get https://xx.xx.xx.xx/v2/: Service Unavailable

reason¶

The reason is probably that docker supports the https protocol by default, and the private library is the http protocol.

solution¶

The mac desktop can be configured with the following code in Preferences->Docker Engine, xx.xx.xx.xx is the address of your own private library.

{
    "insecure-registries":[
        "xx.xx.xx.xx"
    ]
}

For centos system, modify /etc/docker/daemon.json and add the following code.

{
    "insecure-registries":[
        "xx.xx.xx.xx"
    ]
}
