Question

Separate Docker containers for sub domains on a single droplet?

Hi there,

What would be the best scenario for having a MEAN stack web application running on a droplet with sub domains using docker container(s)?

For example:
domain.com (landingspage) (nginx)
api.domain.com (backend API) (node)
app.domain.com (frontend client side) (nginx)

Ideally would be that each sub domain has it’s own container so that we can keep the SoC in mind.

After doing some research we see that there is a way doing this with a nginx reserve proxy as explained here:
https://www.digitalocean.com/community/questions/how-to-host-multiple-docker-containers-on-a-single-droplet-with-nginx-reverse-proxy

Would this be the ideal situation when we having separate repo’s and having an SSL wildcard for the subdomains?

Any help or guidance would be very appreciated :)

Hi there @alifar,

Yes following the steps from that link that you’ve shared would definitely work.

Another approach that you could take is to run your Nginx server in a Docker container as well, that way you would not have to install Nginx on the host itself.

Another thing that you might want to consider is to build a docker-compose file and start all of your containers with one run rather than manually start the containers one by one with the docker run command.

Bobby
