I was wondering about how to establish CI/CD on my project.
What is the best practice for that?

I have server where project works without docker containers.
Laravel covers backend (REST API)
NuxtJS covers frontEnd (SSR + SPA)

Recently I have decided to update our infrastructure: I want to dokerize my project.

So, I organized 4 containers:

• mysql
• php
• nuxtjs
• traefik (back proxy)

That’s runnig on localhost good.

I should say, docker — that’s amazing. I have solve lot of problems with the same env on different computers.

Then, I decided to by a new server: Ubuntu.
I have installed docker and docker-compose.

Right now I am wondering how to organize blue-green delivery:

• I want to minimize lock down while delivering new version of code.
• I want to run CD by commit on my gitlab (I have my own gitlab on other my server)

My questions is:

• is that good way to use just docker-compose but not Kubernetes? I think my project is to small for Kubernetes 🙂 On ther hand I read that Kubernetes already has solved blue-green deployment / logging at setra.

• how to organize blue-green deployment in the best way? Should I run double containers at the same time and after deploy, turn router in traefik to new container?

• I heard about technology DinD (docker in docker). Should I run docker compose in docker-container? Or run docker-composer on the host?
