一个容器杀死另一个

  • 772

我在一辆独轮车上运行多个容器。这些容器使用两个不同的docker-compose. 它们是 api 的副本，唯一的区别是它们使用不同的环境变量运行。同时，当一个容器启动，另一个从deploy_storage-api_1 exited with code 137. 据我了解，内存有问题runtime。但我不知道如何真正理解发生了什么。我试图在 中公开资源docker-compose，但事实证明，没有swarm. 告诉我如何解决这个问题？没有它可以完成swarm吗？我还注意到另外 5-6 个容器在独轮车上旋转。

Dockerfile

RUN apt-get update && apt-get install make
RUN apt-get install -y python3.7 python3-pip
RUN python3.7 -m pip install --upgrade pip
RUN apt-get install -y git

COPY . /app
WORKDIR /app

RUN PIP=pip PYTHON=python3.7 make deps
CMD PIP=pip PYTHON=python3.7 make run

    解决方案非常简单。两个同名的容器可以互相杀死。同时，在一种情况下，他们互相残杀。在另一个，等价的，没有。为什么会发生这种情况，我还没有发现。这就是为什么我问了一个单独的问题。解决办法是这样的：取不同的名字，这样就没有交集了。
