set up a postgres database on a cloud vm, install docker to it, and link in the image

0

Hello, I have not used postrgres, vm, or docker before, but I would like to use this docker image to clone the api and host it on a cloud vm. Someone said I should set up a postgres database on a cloud vm, install docker to it, and link in the image. Can anyone tell me if this is the correct way to go here, and how exactly I can do that? I see web services and postgres databases as options on cloud providers but not sure if I need one or both or how to proceed here. Also how much gb minimum plan do I need to run this to test it? The code is from https://github.com/0xProject/0x-api#database and the image is here on dockerhub https://hub.docker.com/r/0xorg/0x-api Thanks for any insights or help with getting this running!!

Beware the 0x repository your mention is listed as deprecated and unsupported, so I would not trust or use that container in production systems. If you just want a proof of concept, it likely will work fine. When it comes to running containers, it really depends on your needs, and there are several options:

  • You can always spin anything up you want on an Amazon Elastic Compute Cloud (EC2) Instance and manage Docker 100% yourself.
  • Using Amazon Elastic Kubernetes Service (EKS) you can create tasks to run the container. (I don't recommend this for your first time with containers)
  • Using Elastic Container Services(ECS) you can create tasks (where you specify all the required ENV Variables)here and run them on AWS Fargate and are completely serverless. This is a great way to run a container, especially when you are researching options.
  • Using Amazon RDS you can spin up a dedicated Postgres instance that is managed and patched by AWS. This however will not run your API, but it will give you a stable and well-maintained postgres instance.
  • You could run postgres as a container if desired, but I would not recommend it.

As for sizing, I always start with small sizes first and test to see if I need to vertically scale the hardware this keeps costs as low as possible . With AWS you can vertically scale an instance quite easily. Using Fargate with ECS you can also specify the size of the Task, and I typically do the same things.
