The fastest way to set up a Nano node is via a docker container from DockerHub. You'll need a semi-recent version of Docker, Client Version ~ 1.5.0.
https://docs.docker.com/engine/installation
sudo docker pull nanocurrency/nanosudo docker run -d -p 7075:7075/udp -p 7075:7075 -p [::1]:7076:7076 -v ~:/root --restart=unless-stopped nanocurrency/nanoThis command:
- Starts the docker container as a daemon
-d - Maps the network activity port
-p 7075:7075/udp - Maps the bootstrapping TCP port
-p 7075:7075 - Maps the RPC control port to the local adapter only
-p [::1]:7076:7076 - Maps the host's home directory to the guest /root directory
~:/root - Restarts the container if it crashes
--restart=unless-stopped - Specifies the container to execute
nanocurrency/nano
This will put the data in a permanent location in your hosts's home directory, outside the docker container.
If you get Error starting userland proxy: port is not a proto:IP:port: 'tcp:[:'. or want to expose IPv4 port, use -p 127.0.0.1:7076:7076.
If you get create ~: volume name is too short, names should be at least two alphanumeric characters. replace the ~ with the full pathname such as /Users/someuser.
You'll need the container ID for the following commands. You can get it with sudo docker ps e.g. d9416b274092. Replace <CONTAINERID> with that ID.
First create a new wallet:
sudo docker exec <CONTAINERID> /usr/bin/rai_node --wallet_createYou should get a wallet ID which you need in the next step.
sudo docker exec <CONTAINERID> /usr/bin/rai_node --account_create --wallet=<WALLETID>You get a new Nano address starting with xrb_1234… back.
To get your seed execute:
sudo docker exec <CONTAINERID> /usr/bin/rai_node --wallet_decrypt_unsafe --wallet=<WALLETID>More information about the wallet backup is available here: Wallet Backups
Restart your container afterwards:
sudo docker restart <CONTAINERID>You can use the RPC interface on the local host via curl.
For example the version of the node:
curl -d '{ "action" : "version" }' [::1]:7076Or the blockcount:
curl -d '{ "action" : "block_count" }' [::1]:7076All available RPC commands are listed here: RPC protocol
To update your container you need to rebuild it.
Make sure that you have your seed backup up!
First stop your old container:
sudo docker stop <CONTAINERID>Then remove it:
sudo docker rm <CONTAINERID>Then pull the new image and run the image just like you did at first start.
You can find reference material for using docker here: https://docs.docker.com/engine/reference/commandline/
You can create a custom name for your container at the docker runcommand by adding e.g. --name nanonode.
Once set up, using bashrc to create an alias can save you time.
For example (when nanonode is the name your docker container):
sudo docker exec nanonode /usr/bin/rai_node --diagnostics
Can be shortened to:
rai --diagnostics
By editing ~/.bashrc to add the alias:
alias rai='sudo docker exec nanonode /usr/bin/rai_node'
