Navcoin Full Node for Docker

Navcoind + Wallet + WebUI docker image, thats run the Navcoin Full Node to earn Proof of Stake rewards.

Requirements

• Any phisical or virtual machine that support docker.
• 2GB to store the blockchain files (warning, the chain is always growing).
• And 1 GB of RAM.

Quick start

1. First you need to create a named volume navcoin-data to persist the blockchain and wallet files:

     docker volume create --name=navcoin-data

Or directly you can use a specific directory from the host, i prefer named volumes.
For know the difference, read this: Manage data in containers.

So if you want to reboot, upgrade or destroy the container, that files will be safe.

2. Create the container:

     docker run -v navcoin-data:/navcoin --name=navcoin-full-node -d \
                -p 44440:44440 \
                -p 127.0.0.1:44444:44444 \
                -p 8080:443 \
                sebaponti/docker-navcoind

3. Check if the container its susefuly created, and its running:

     docker ps

4. You can then access the daemon's output thanks to the docker logs command.

     docker logs -f navcoin-full-node

5. Put this https://localhost:8080 in your browser, add the self-signed certificate and dont forget to change the default password for the Web UI.

Create a new SSL certificate

The smokebox web application has ssl-mod enabled for default, the certificate its created in the image building process, but if you want to create a new one, run this command:

     docker exec -it navcoin-full-node openssl req -x509 -nodes -days 3650 \
          -newkey rsa:2048 -out /etc/apache2/ssl/navpi-ssl.crt \
          -keyout /etc/apache2/ssl/navpi-ssl.key

Then we need to flush and reload apache:

     docker stop navcoin-full-node && docker start navcoin-full-node

Custom Building (optional)

You can build the image with custom parameters like id's of your unprivileged user,
clone the repository and build the image with this args:

     docker build --build-arg USER_ID=$( id -u ) --build-arg GROUP_ID=$( id -g ) .

By default the image is building with the user and group id = 1000.

Update

To get the latest version of this image run:

     docker pull sebaponti/docker-navcoind
