在AWS EC2中运行自定义的mongo容器

Question

I'm trying to running a cluster containing two containers, one with an image that runs a node.js server, and one container for a mongo db.

I'm following this tutorial , which states to use registry.hub.docker.com/library/mongo:latest as the image url for the mongodb.

Now, I have a problem. Locally, when I run the mongo container on my pc, I use the following script , which does two things:

1. Executes docker run with a mongo image, stating --replSet in the arguments
2. Runs two shell commands - initating the replica set, and setting up an initial user.

The hard part I can't wrap my head around, is the --replSet part.
When I run the container the the official mongodb image, it initiates mongod in some default way.

Say, I create a new Dockerfile , which states FROM mongo:latest .
To my limited understanding, the rest of the things that will happen in the custom Dockerfile , the mongod is already ran. Is there any way I can modify that way it is executes in mongo:latest , or modify an already active mongod to allow the --replSet option?

The shell commands on the mongo shell, as far as I understand, won't be a problem, since this is just a couple of RUN commands in the Dockerfile .

Thanks in advance for helping!

我设法仅在ECS任务的网络模式设置为bridged下运行它。
