# Docker 上下文
|
||||
|
||||
## 基础命令
|
||||
|
||||
> 示例新上下文名为: docker-node2
|
||||
|
||||
- 查看当前上下文
|
||||
|
||||
```bahs
|
||||
docker context ls
|
||||
```
|
||||
|
||||
- 详细查看上下文信息
|
||||
|
||||
```bash
|
||||
docker context inspect default
|
||||
```
|
||||
|
||||
- 创建新的上下文
|
||||
|
||||
```bash
|
||||
docker context create docker-node2 --docker host=tcp://docker:2375
|
||||
```
|
||||
|
||||
- 切换上下文
|
||||
|
||||
```bash
|
||||
docker context use docker-node2
|
||||
```
|
||||
|
||||
> 通过变量切换
|
||||
>
|
||||
> ```bash
|
||||
> export DOCKER_CONTEXT=docker-node2
|
||||
> ```
|
||||
>
|
||||
> 全局`--context`标志覆盖上下文
|
||||
>
|
||||
> ```bash
|
||||
> docker --context production container ls
|
||||
> ```
|
||||
|
||||
- 导出上下文
|
||||
|
||||
```bash
|
||||
docker context export docker-node2
|
||||
```
|
||||
|
||||
- 导入上下文
|
||||
|
||||
```bash
|
||||
docker context import docker-node2 docker-node2.dockercontext
|
||||
```
|
||||
|
||||
- 更新上下文
|
||||
|
||||
```bash
|
||||
docker context update docker-node2 --description "Test context"
|
||||
```
