在docker-compose设置中调用redis-cli [英] Calling redis-cli in docker-compose setup

问题描述

我运行官方Redis映像 https://hub.docker.com/_/redis/ 在 docker-compose 设置中。

I run the official Redis image https://hub.docker.com/_/redis/ in a docker-compose setup.

myredis:
  image: redis

如何使用docker-compose在该映像上运行 redis-cli ？

我尝试了以下操作，但未连接：

How can run redis-cli with docker-compose on that image?
I tried the following, but it didn't connect:

docker-compose run myredis redis-cli
> Could not connect to Redis at 127.0.0.1:6379: Connection refuse

图片的文档显示我应该运行：

The docs of the image says that I should run:

docker run -it --rm \
--link some-redis:redis \
redis \
sh -c 'exec redis-cli -h "$REDIS_PORT_6379_TCP_ADDR" -p "$REDIS_PORT_6379_TCP_PORT"'

这如何转换为 docker-compose run ？

推荐答案

这将覆盖默认 CMD [ redis-server] ：您尝试在容器中运行 redis-cli redis服务器从未执行过。

That would override the default CMD [ "redis-server" ]: you are trying to run redis-cli on a container where the redis-server was never executed.

如此处所述，您还可以测试：

docker exec -it myredis redis-cli

来自docker-compose，如前所述在此docker / compose问题2123中：

From docker-compose, as mentioned in this docker/compose issue 2123:

rcli:
  image: redis:latest
  links:
    - redis
  command: >
     sh -c 'redis-cli -h redis '

这也应该起作用：

This should also works:

rcli:
  image: redis:latest
  links:
    - redis
  command: redis-cli -h redis

OP ivoba 确认（在评论中），最后一种形式有效。

然后：

As the OP ivoba confirms (in the comments), the last form works.
Then:

docker-compose run rcli

ivoba还添加：

docker-compose run redis redis-cli -h redis 在容器运行时也起作用。

这样，不必声明单独的 rcli 容器。

docker-compose run redis redis-cli -h redis works also when the containers are running.
This way its not necessary to declare a separate rcli container.
