Docker
I like to host all of my services using docker.
Installation
Installation of docker within Ubuntu Server is done so by following the instructions on the official docker documentation site
I predominantly use Ubuntu Server which is based off Debian but I am starting to switch to using actual Debian itself.
Once installed, running docker --version should then return something similar to the following:
Network Configuration
Before spinning up some docker containers, I need to ensure I have setup my docker networks.
I use 3 docker networks (2 on titan and 1 on cuthbert)
TiTAN
TiTAN runs a Reverse Proxy in the form of Traefik. To ensure that all applications (that need to be proxied) pass through Traefik, I would need to associate them with this network.
The creation of the network is a simple command and is one that specifies a subnet.
The reason for specifying a subnet is so I can provide a static IP Address to each of my services. This also assists with connectivity between containers and keeps everything organised.
docker network create --subnet 172.19.0.0/24 proxy
docker network create --subnet 172.18.0.0/24 monitoring
This creates a /24 subnet named proxy and a /24 subnet named monitoring
Cuthbert
The "cuthbert-network" docker network has been created for all of the containers running on cuthbert
Just like TiTAN containers, they have all been provided with static IP Addresses.
As this is a totally seperate system, I'm unable to associate docker containers here with the network that traefik is running on. Therefore, any container that needs to run through traefik, a dynamic file needs to be created.
This creates a /24 subnet named cuthbert-network
Docker Commands
I deploy all of my docker containers using docker compose.
This is where I will write out everything the container needs in a YAML file.
To pull and deploy the image according to the details in the YAML, from the same directory as where the compose file resides, I would run the following command:
The -d at the end will run the container detached meaning the terminal window can be closed and the container will continue running.
Should I need to make changes to my YAML configuration (change some environment settings or change the docker image being used), I can re-deploy the container with a similar command:
This will ensure the container is re-created.
With the exception of Traefik & Monitoring on TiTAN, all of my compose files reside in the following locations
