PrometheusDockerWSL

Docker on Windows using WSL

Some useful docker commands

docker logs containerid
docker system prune
docker rm containerid
docker rmi -f imagid

issue with not reading config file on host

chmod 777 directory
chmod 777 file

/etc/wsl.conf

[automount]
root = /
enabled = true
options = "metadata"

Make sure c drive is mounted

ls -la /c
pwd
sudo mkdir prometheus
sudo mkdir prometheus_data
sudo nano docker-compose.yml

in below docker compose file in volume section what it means is local folder on host is pointing to location on container

create a simple Prometheus configuration file in home directory
/home/username

cat < prometheus.yml global: scrape_interval: 10s evaluation_interval: 10s

scrape_configs: - job_name: ‘prometheus’ static_configs: - targets: [‘localhost:9090’] EOF

This tells the Prometheus server to scrape itself on port 9090.

Now let's create a Dockerfile that adds this on top of the prom/prometheus image:

cat < Dockerfile FROM prom/prometheus

# Add in the configuration file from the local directory.

ADD prometheus.yml /etc/prometheus/prometheus.yml EOF

Next we can build and run it:

docker build -t prometheus_simple . docker run -p 9090:9090 prometheus_simple

If you visit http://localhost:9090/consoles/prometheus.html you’ll see the Prometheus console!

CTL C to stop prometheus docker images

docker rm prom/prometheus

cd /c/Users/ka0823575/Documents cd /home/kk docker-compose.yml resides here

docker-compose up docker-compose up -d docker-compose down

### Troubleshooting Docker on Windows
Sometimes u have issues with volumes and that could be because of changing the windows logon password, to fix do this

Goto Settings Shared Drives Reset Credential Check C drive Restart Docker

use bridge driver if you dont want to use sware mode for sware mode use driver overlay ### References
