oauth2-proxy: A Go repository from draeron

A reverse proxy and static file server that provides authentication using Providers (Google, Keycloak, GitHub and others) to validate accounts by email, domain or group.

Note: This repository was forked from bitly/OAuth2_Proxy on 27/11/2018. Versions v3.0.0 and up are from this fork and will have diverged from any changes in the original fork. A list of changes can be seen in the CHANGELOG.

Note: This project was formerly hosted as pusher/oauth2_proxy but has been renamed as of 29/03/2020 to oauth2-proxy/oauth2-proxy. Going forward, all images shall be available at quay.io/oauth2-proxy/oauth2-proxy and binaries will be named oauth2-proxy.

Installation

Choose how to deploy:

a. Using a Prebuilt Binary (current release is v7.6.0)

b. Using Go to install the latest release
```
$ go install github.com/oauth2-proxy/oauth2-proxy/v7@latest
```
This will install the binary into $GOPATH/bin. Make sure you include $GOPATH in your $PATH. Otherwise your system won't find binaries installed via go install

c. Using a Prebuilt Docker Image (AMD64, PPC64LE, S390x, ARMv6, ARMv7, and ARM64 available)

d. Using a Pre-Release Nightly Docker Image (AMD64, PPC64LE, S390x, ARMv6, ARMv7, and ARM64 available)

e. Using the official Kubernetes manifest (Helm)

Prebuilt binaries can be validated by extracting the file and verifying it against the sha256sum.txt checksum file provided for each release starting with version v3.0.0.
```
sha256sum -c sha256sum.txt 2>&1 | grep OK
oauth2-proxy-x.y.z.linux-amd64: OK
```
Select a Provider and Register an OAuth Application with a Provider
Configure OAuth2 Proxy using config file, command line options, or environment variables
Configure SSL or Deploy behind a SSL endpoint (example provided for Nginx)

Security

If you are running a version older than v6.0.0 we strongly recommend you please update to a current version. See open redirect vulnerability for details.

Images

From v7.6.0 and up the base image has been changed from Alpine to GoogleContainerTools/distroless. This image comes with even fewer installed dependencies and thus should improve security. The image therefore is also slightly smaller than Alpine. For debugging purposes (and those who really need it (i.e. armv6)) we still provide images based on Alpine. The tags of these images are suffixed with -alpine.

Since 2023-11-18 we provide nightly images. These images are build and pushed nightly to quay.io/oauth2-proxy/oauth2-proxy-nightly from master. These images should be considered alpha and therefore should not be used for production purposes unless you know what you're doing.
