What is this container for?

This container runs Nginx as a non-root user serving Element web-UI.

Why use this container?

Simply put, this container has been written with simplicity and security in mind.

Many community containers run unnecessarily with root privileges by default and don't provide help for dropping unneeded CAPabilities either. On top of that, overly complex shell scripts, monolithic designs and unofficial base images make it harder to verify the source among other issues.

To remedy the situation, these images have been written with security and simplicity in mind.

Requirement	Status	Details
Don't run as root	✅	Never run as root unless necessary.
Transparent build process	✅	For verifying that the container matches the code. See GitLab CI.
Official base image	✅
Drop extra CAPabilities	✅	See docker-compose.yml
No default passwords	✅	No static default passwords. That would make the container insecure by default.
Support secrets-files	✅	Support providing e.g. passwords via files instead of environment variables.
Handle signals properly	✅
Simple Dockerfile	✅	No overextending the container's responsibilities. And keep everything in the Dockerfile if reasonable.
Versioned tags	✅	Offer versioned tags for stability.

Running this container

See the example docker-compose.yml in the source repository.

Supported tags

See the Tags tab on Docker Hub for specifics. Basically you have:

• The default latest tag that always has the latest changes.
• Minor versioned tags (follow Semantic Versioning), e.g. 1.1 which would follow branch 1.1.x on GitHub.

Configuration

You'll need to provide the configuration for the container at /opt/element-web/config.json (as shown in docker-compose.yml).
Sample configuration files can be found in element-web root directory or in the official repository.
