conduit/docker

Docker

Note: To run and use Conduit you should probably use it with a Domain or Subdomain behind a reverse proxy (like Nginx, Traefik, Apache, ...) with a Lets Encrypt certificate.

This text is also available at the official wiki.

Build & Dockerfile

The Dockerfile provided by Conduit has two stages, each of which creates an image.

1. Builder: Builds the binary from local context or by cloning a git revision from the official repository.
2. Runtime: Copies the built binary from Builder and sets up the runtime environment, like creating a volume to persist the database and applying the correct permissions.

The Dockerfile includes a few build arguments that should be supplied when building it.

ARG LOCAL=false
ARG CREATED
ARG VERSION
ARG GIT_REF=HEAD

• CREATED: Date and time as string (date-time as defined by RFC 3339). Will be used to create the Open Container Initiative compliant label org.opencontainers.image.created. Supply by it like this $(date -u +'%Y-%m-%dT%H:%M:%SZ')
• VERSION: The SemVer version of Conduit, which is in the image. Will be used to create the Open Container Initiative compliant label org.opencontainers.image.version. If you have a Cargo.toml in your build context, you can get it with $(grep -m1 -o '[0-9].[0-9].[0-9]' Cargo.toml)
• LOCAL: (Optional) A boolean value, specifies if the local build context should be used, or if the official repository will be cloned. If not supplied with the build command, it will default to false.
• GIT_REF: (Optional) A git ref, like HEAD or a commit ID. The supplied ref will be used to create the Open Container Initiative compliant label org.opencontainers.image.revision and will be the ref that is cloned from the repository when not building from the local context. If not supplied with the build command, it will default to HEAD.

To build the image you can use the following command

docker build . -t conduit_homeserver:latest --build-arg CREATED=$(date -u +'%Y-%m-%dT%H:%M:%SZ') --build-arg VERSION=$(grep -m1 -o '[0-9].[0-9].[0-9]' Cargo.toml)

which also will tag the resulting image as conduit_homeserver:latest. Note: it ommits the two optional build-args.

Run

After building the image you can simply run it with

docker run conduit_homeserver:latest -p 8448:8000 -v db:/srv/conduit/.local/share/conduit -e ROCKET_SERVER_NAME="localhost:8000"

For detached mode, you also need to use the -d flag. You can pass in more env vars as are shown here, for an overview of possible values, you can take a look at the docker-compose.yml file. If you just want to test Conduit for a short time, you can use the --rm flag, which will clean up everything related to your container after you stop it.

Docker-compose

If the docker command is not for you or your setup, you can also use one of the provided docker-compose files. Depending on your proxy setup, use the docker-compose.traefik.yml including docker-compose.override.traefik.yml or the normal docker-compose.yml for every other reverse proxy.

Build

To build the Conduit image with docker-compose, you first need to open and modify the docker-compose.yml file. There you need to comment the image: option and uncomment the build: option. Then call docker-compose with:

CREATED=$(date -u +'%Y-%m-%dT%H:%M:%SZ') VERSION=$(grep -m1 -o '[0-9].[0-9].[0-9]' Cargo.toml) docker-compose up

This will also start the container right afterwards, so if want it to run in detached mode, you also should use the -d flag. For possible build-args, please take a look at the above Build & Dockerfile section.

Run

If you already have built the image, you can just start the container and everything else in the compose file in detached mode with:

docker-compose up -d
