Docker builds of cardano-wallet are available on DockerHub.

Downloading the Docker image

To get the latest release of cardano-wallet-itn, run:

docker pull inputoutput/cardano-wallet:jormungandr

Running the Docker container for cardano-wallet-itn

To run basic CLI commands, use:

docker run --rm inputoutput/cardano-wallet:jormungandr --help

See Wallet Command Line Interface for full documentation of the CLI.

Running a cardano-wallet server requires setting up a state directory with a jormungandr config file.

This example uses the itn_rewards_v1 testnet.

  1. Set up a state directory with the network config on the Docker host.

    mkdir $HOME/state-docker
wget -P $HOME/state-docker https://hydra.iohk.io/job/Cardano/iohk-nix/jormungandr-deployment/latest/download/1/itn_rewards_v1-config.yaml

  2. Run the cardano-wallet server and jormungandr:

    docker run \
    --publish 127.0.0.1:8090:8090 \
    --volume $HOME/state-docker:/data \
    --env TMPDIR=/data \
    --rm \
    inputoutput/cardano-wallet \
    launch \
    --listen-address 0.0.0.0 \
    --state-dir /data \
    --genesis-block-hash 8e4d2a343f3dcf9330ad9035b3e8d168e6728904262f2c434a4f8f934ec7b676 \
    -- --config /data/itn_rewards_v1-config.yaml

    Explanation of the arguments:

    • --publish 127.0.0.1:8090:8090 - exposes the API server port from the container to the Docker host.

    • --volume $HOME/state-docker:/data - mounts the ~/state-docker directory on the Docker host to /data inside the container.

    • --env TMPDIR=/data - work around a temp directory issue (#1262). Alternatively, you may mount an additional volume on your own temporary directory with --volume /tmp:/tmp.

    • --listen-address 0.0.0.0 - ensures that the API server binds to the Docker network interface, so that the server can be accessed from outside of the container.

    • --state-dir /data - use the data volume for chain and wallet databases.

  3. Wait for the log message Wallet backend server listening on 0.0.0.0:8090 to be shown (it may take 30-60 minutes for jormungandr to bootstrap).

    Then in another shell, on the Docker host, run:

    curl http://localhost:8090/v2/network/information

    The cardano-wallet API server should return its status as JSON.

Naming scheme

The following tags are pushed to DockerHub.

Tag Network node backend Version
inputoutput/cardano-wallet:jormungandr Jörmungandr Latest GitHub release
inputoutput/cardano-wallet:dev-master-jormungandr Jörmungandr Latest revision of master branch
inputoutput/cardano-wallet:2020.1.7-jormungandr Jörmungandr v2020-01-07 (for example)
inputoutput/cardano-wallet:e902913750f763ac3dcb37f57fa35154db2934eb-jormungandr Jörmungandr A certain revision of the master branch (e902913 for example).

Building the Docker image locally

Ensure that you have Nix installed and the IOHK binary cache enabled (instructions).

Then run this command from the cardano-wallet git repo:

docker load -i $(nix-build -A dockerImage.jormungandr --no-out-link)

If you have no local changes, the build should be downloaded from the IOHK binary cache then loaded into your local Docker image storage.

Inspecting the contents of the Docker image

The default entrypoint of the image is /bin/start-cardano-wallet-jormungandr. If you need to run a shell inside the Docker image, use the bash shell as the entrypoint:

docker run --rm -it --entrypoint bash inputoutput/cardano-wallet:jormungandr
