Acra from Docker images

Launching Acra from Docker images #

You can use containers with Acra. Acra works well with Docker.

Precautions #

Storing keys safely when using Docker is problematic. Docker is immutable while Zones/keys are not. This means that you might want to attach some storage and end up making the keys accessible to attackers.

There are multiple ways to solve this problem, and it can be addressed in a convenient and secure fashion depending on your specific infrastructure.

Images #

There are pre-built images that you can obtain from the Docker Hub Cossack Labs repository:

Docker images have tags. When we build them, we set appropriate tags for each image:

  • rolling tags:

    • stable and latest - stable branch, recommended, default;
    • master and current - master branch of Acra GitHub repository.
  • fixed tags:

    • <full_commit_tag> - specify the exact commit in the repository;
    • <version> - choose version tag.

An image usually has two (commit, version) or four (+ branch, latest/current) tags.

All these images can be used traditionally:

docker run <options> cossacklabs/<component> <arguments>

Usually you do not need to do it, but you may want to build all the images from current sources manually. To do that, type:

make docker-build
