techthinkerorg/squid repository overview

⁠Squid

Squid is a proxy cache server.

⁠Uses

  • Open Chromium browser with proxy
chromium --proxy-server="https=server-ip:3128;http=server-ip:3128"

  • For firefox, use proxy settings and use same http and http proxy as server-ip and port 3128.

  • Note: Login credentials will ask on Prompt in browser if required. If you need tunnel you can use ssh. ssh -L 3128:server-ip:3128 username@server-ip. Then in your new proxy host will be localhost and port will be 3128.

⁠Available Versions:

  • edge and v1.0.0 version has very basic squid. It is not configured, So, squid.conf need to download and put in deployment. Kubernetes deployments are based on these versions.
  • v2.0.0 has pre-configured authentication setup.

⁠Note

  • For v2.0.0 or higher you do not need to download and put squid.conf.
  • Environment variables - AUTH_REQUIRED=true/false, USERNAME and PASSWORD.

⁠Docker-compose

version: "3"

services:
  squid:
    image: techthinkerorg/squid:v2.0.0
    container_name: squid
    ports:
      - "3128:3128"
    environment:
      - AUTH_REQUIRED=true
      - USERNAME=squid

⁠Deploy with Kubernetes

Works with any Kubernetes; if you don't have one, we recommend you install MicroK8s and microk8s.enable dns storage then snap alias microk8s.kubectl kubectl.

Download squid.conf⁠ and squid-deployment.yml⁠ and set containers.squid.image in squid-deployment.yml to your chosen channel tag (e.g. ubuntu/squid:5.2-22.04_beta), then:

kubectl create configmap squid-config --from-file=squid=squid.conf
kubectl apply -f squid-deployment.yml

You can now access the squid proxy on port 3128
