docker load -i和docker push registry
时间: 2023-12-04 13:40:40 浏览: 46
`docker load -i`命令用于将一个镜像加载到Docker中。其中,`-i`选项表示从一个文件中读取镜像,后面紧跟着文件名。例如,如果要将名为`myimage.tar`的镜像加载到Docker中,可以使用以下命令:
```shell
docker load -i myimage.tar
```
`docker push`命令用于将本地的镜像推送到远程仓库中。其中,`registry`是远程仓库的名称。例如,如果要将名为`myimage`的本地镜像推送到名为`registry`的远程仓库中,可以使用以下命令:
```shell
docker push registry/myimage
```
需要注意的是,在使用`docker push`命令之前,需要先使用`docker login`命令登录到远程仓库中。具体命令如下:
```shell
docker login registry
```

上面的输出内容可以分为两部分:
1. Options:Docker 客户端的选项,包括:
- `--config`: 指定客户端配置文件的位置。
- `-c, --context`: 指定连接到守护进程的上下文。
- `-D, --debug`: 启用调试模式。
- `--help`: 打印使用帮助。
- `-H, --host`: 指定要连接的守护进程套接字。
- `-l, --log-level`: 设置日志记录级别。
- `--tls`: 使用 TLS。
- `--tlscacert`: 指定信任的 CA 证书。
- `--tlscert`: 指定 TLS 证书文件的路径。
- `--tlskey`: 指定 TLS 密钥文件的路径。
- `--tlsverify`: 使用 TLS 并验证远程主机。
- `-v, --version`: 打印版本信息并退出。
2. Management Commands 和 Commands:Docker 的管理命令和常规命令。其中,管理命令用于管理 Docker 的各种资源,常规命令用于执行各种操作,例如创建容器、运行容器、获取容器日志等等。可以通过`docker COMMAND --help`来查看每个命令的详细说明。
docker导入所有 镜像,并推送到私有仓库
首先,使用 `docker images` 命令列出所有本地镜像。
然后,使用 `docker save` 命令将每个镜像保存为一个 tar 文件,例如:
```
docker save -o image1.tar image1
docker save -o image2.tar image2
...
```
接下来,使用 `docker load` 命令导入这些镜像:
```
docker load -i image1.tar
docker load -i image2.tar
...
```
最后,使用 `docker tag` 命令将这些镜像标记为私有仓库的地址,并使用 `docker push` 命令推送到私有仓库:
```
docker tag image1 my-registry.com/image1
docker push my-registry.com/image1
docker tag image2 my-registry.com/image2
docker push my-registry.com/image2
...
```
注意:在推送镜像到私有仓库之前,需要先登录到该仓库,使用 `docker login` 命令进行登录。
