MISP Docker image

MISP container (Docker) image focused on high performance and security based on AlmaLinux, ready for production.

This image contains the latest version of MISP and the required dependencies. Image is intended as immutable, which means that it is not possible to update MISP from the user interface and instead, an admin should download a newer image.

Key features

• 🎩 Image is based on AlmaLinux, so perfectly fits your infrastructure if you use CentOS or RHEL as a host system
• ✅ Modern MISP features are enabled by default (like advanced audit log or storing settings in the database)
• 👩‍💻 Integrated support for OpenID Connect (OIDC) authentication
• 🔒️ PHP is by default protected by Snuffleupagus extensions with rules tailored to MISP
• 🚀 Optional extensions and configurations that will make MISP faster are enabled
• 📓 Integrated support for logging into ECS format, exceptions to Sentry and forwarding logs to syslog server
• 🧪 The final image is automatically tested, so every release should work as expected
• 🏛 Build for amd64 (x86_64) and arm64 (aarch64)

Usage

First, you have to install Docker. Follow these manuals how to install Docker on your machine. Windows, macOS, or Linux are supported. For Linux, you also need to install Docker Compose V2, on macOS or Windows is already included in Docker itself. Or you can use Docker Compose V1, but then you have to use all commands with a dash (so docker-compose instead of docker compose).

Usage for testing

Docker Compose file defines MISP itself, MISP Modules, MariaDB and Redis, so everything you need to run MISP. Just run:

curl --proto '=https' --tlsv1.2 -O https://raw.githubusercontent.com/NUKIB/misp/main/docker-compose.yml
docker compose up -d

Then you can access MISP in your browser by accessing http://localhost:8080. The default user after installation is [email protected] with the password admin.

To delete all volumes after testing, run:

docker-compose down -v

Updating

When a new MISP is released, also new container image is created. For updating MISP and MISP Modules, just run these commands in the folder that contains docker-compose.yml file. These commands will download the latest images and recreate containers. All data will be preserved.

docker compose pull
docker compose up -d

Usage in a production environment

For production usage, please:

• change passwords for MariaDB and Redis,
• modify environment variables to requested values,
• deploy reverse proxy (for example nginx) before MISP to handle HTTPS connections.
  • do not forget to send proper X-Forwared-For header

Usage in air-gapped environment

MISP by default does not require access to Internet. So it is possible to use MISP in air-gapped environment or an environment with blocked outgoing connections. Check AIR-GAP.md for more information.

Image building

If you don't trust image built by GitHub Actions and stored in GitHub Container Registry or you want to build a different MISP version, you can build this image by yourself:

docker build --build-arg MISP_VERSION=v2.4.152 -t ghcr.io/nukib/misp https://github.com/NUKIB/misp.git#main

If you don't like AlmaLinux, you can use as a base image different distribution that is compatible with AlmaLinux 8, like CentOS Stream or Rocky Linux:

docker build --build-arg BASE_IMAGE=quay.io/centos/centos:stream8 -t ghcr.io/nukib/misp https://github.com/NUKIB/misp.git#main

Logging

Logging is important to keep your MISP secure and in good condition. Check detailed manual how to configure logging
