Squid | Ubuntu

Current Squid Docker Image from Canonical, based on Ubuntu. Receives security updates and rolls to newer Squid or Ubuntu release. This repository is free to use and exempted from per-user rate limits.

About Squid

Squid is a caching proxy for the Web supporting HTTP, HTTPS, FTP, and more. It reduces bandwidth and improves response times by caching and reusing frequently-requested web pages. Squid has extensive access controls and makes a great server accelerator. It runs on most available operating systems, including Windows and is licensed under the GNU GPL.

Tags and Architectures

!LTS Up to 5 years of free security maintenance on LTS channels.

!ESM Up to 10 years of customer security maintenance from Canonical's restricted repositories.

Channel Tags	Supported until	Currently	Architectures
`5.2-22.04_beta`	-	Squid 5.2 on Ubuntu 22.04 LTS	`amd64`, `arm64`, `ppc64el`, `s390x`
`4.13-21.10_beta`	-	Squid 4.13 on Ubuntu 21.10 null	`amd64`, `arm64`, `ppc64el`, `s390x`
`4.10-20.04_beta`	-	Squid 4.10 on Ubuntu 20.04 LTS	`amd64`, `arm64`, `ppc64el`, `s390x`
`track_risk`

Channel Tags shows the most stable channel for that track ordered stable, candidate, beta, edge. More risky channels are always implicitly available. So if beta is listed, you can also pull edge. If candidate is listed, you can pull beta and edge. When stable is listed, all four are available. Images are guaranteed to progress through the sequence edge, beta, candidate before stable.

Commercial use and Extended Security Maintenance channels

If your usage includes commercial redistribution, or requires ESM or unavailable channels/versions, please get in touch with the Canonical team (or using ***).

Usage

Launch this image locally:

sh
docker run -d --name squid-container -e TZ=UTC -p 3128:3128 ubuntu/squid:5.2-22.04_beta

Access your Squid proxy at localhost:3128.

Parameters

Parameter	Description
`-e TZ=UTC`	Timezone.
`-p 3128:3128`	Expose the proxy service
`-v /path/to/logs:/var/log/squid`	Volume to store squid logs
`-v /path/to/data:/var/spool/squid`	Volume to store the squid cache
`-v /path/to/main/config:/etc/squid/squid.conf`	Main squid configuration file
`-v /path/to/config/snippet:/etc/squid/conf.d/snippet.conf`	Configuration snippets included by squid.conf

Testing/Debugging

To debug the container:

sh
docker logs -f squid-container

To get an interactive shell:

sh
docker exec -it squid-container /bin/bash

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:

sh
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
