admin tool

Collection of powerful admin tools easy to deploy.

docker

I mainly use docker to deploy services since it is easy to test the container before sending it in production. Recently is more and more common to have different architectures and while some years ago was common to run everything on intel now compatibility with ARM, AMD and apple chips needs to be proved. The work moves from writing code to set up configuration and although the work doesn't require much development requires a lot of testing and performance profiling. All projects have a dedicated folder for the deployment of that service and the useful configuration files. `docker` and `docker compose` have different logic and different usability and I prefer to distinguish the use. Although the two commands have the same capabilities I prefer to clearly distinguish the use to make the project more readable. The logic I use is the following:

Dockerfile
to create the container by loading an image and install libraries. Entry-point most of the time
docker compose
to administrate more containers, expose ports and define networks

processes

We can list the active process by simply running the command: 

docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

And this is the current setup I have running on this laptop

docker network

We can list the active process by simply running the command: 

docker network list
NETWORK ID NAME DRIVER SCOPE
63db087931ed bridge bridge local  
79eb94f48e06 host host local  
4c78f2856d14 llama_cpp_default bridge local  
1a01f0f0d2f7 none null local  
1bf3ddec6244 ollama_default bridge local  
7d5834e09e3b webserver-net bridge local  
95f40f2ec001 webserver_webserver-net bridge local  

Where webserver-net is where nginx routes the different end-points to the appropriate containers.

docker admin

Stop all containers 

docker stop $(docker ps -aq)

Delete all containers 

#docker rm -f $(docker ps -q)
docker rm $(docker ps -aq)

nginx

Nginx is a quick a reliable web-server. I used apache in the past but the language was always hard to interpret and traefik which is just a reverse proxy and has limited usage.

local LLMs

Unload all models and free VRAM 

local model_name=$(ollama ps | awk 'NR==2 {print $1}')
if [ -z "$model_name" ]; then
  echo "No model is currently loaded."
  return 1
fi
curl http://localhost:11434/api/generate -d "{\"model\": \"$model_name\", \"keep_alive\": 0}}
