These files are intended to provide a ready-to-use consul environment based on Docker.
The Dockerfile aims to be generic, easily extensible and used according to the user's will.
Let's start by building the Docker Image:
From here you got a new shiny Docker Image of a consul agent you can play with:
The Docker Image you just created is based on Alpine distribution and its total size is 30.21 MB.
This is lightweight and that works, though I would not use it in production as it is because of my special needs. That is why you can override the consul configuration in command line without specifying a configuration file that would force you to create the Docker Image again.
Let's say you would like to change the node name of the consul server:
Nevertheless, you would have to specify TONS of arguments in command line, and that is not really practical.
That is why you should directly use the Compose file instead.
The present Compose file sets up a basic consul cluster composed of three services:
- one consul agent in server & boostrap mode
- two consul agents server mode & joining the first one
+-------------------+ +-------------------+ +-------------------+
| | | | | |
| consul-01 |<-->| consul-02 |<-->| consul-03 |
| | | | | |
+-------------------+ +-------------------+ +-------------------+
But you can use it as you want in adding or updating provided services by editing this very file.
Using this Compose file is as easy as:
