关于mongodb：Docker-compose depend_on

Docker-compose depend_on

我有一个MongoDB服务和一个使用Docker Compose运行的测试服务：

1
2
3
4
5
6
7
8
9
10

services:
mongo:
image: myrepo/mongo
ports:
-"27017:27017"
test:
depends_on:
- mongo
image: myrepo/elixir-tests
command: sh start.sh

在start.sh脚本中，我尝试运行：

1	mongo 172.20.0.10:27017/wc-app-sandbox --eval"printjson(....))"

但我得到以下错误：

1	start.sh: 10: start.sh: mongo: not found

我的问题是：为什么会出错-depends-on属性是否假定自动包含服务依赖项？如前所述：

depends_on

Express dependency between services, which has two effects:

docker-compose up will start services in dependency order. In the
following example, db and redis will be started before web.
docker-compose up SERVICE will automatically include SERVICE’s
dependencies. In the following example, docker-compose up web will
also create and start db and redis.

这个错误并不意味着"我找不到到到Mongo容器的路由"，它意味着"我找不到mongo执行bin"。可能图像myrepo/elixir-tests不包含mongo-client。尝试将它安装到容器中。

Mongo连接字符串应该类似于mongo mongo:27017/wc-app-sandbox --eval"printjson(....))"。
