From the official cardano-node setup tutorials from IOHK. The container downloads and builds the cardano-node. It can start either a block-producing node or a relay node, or both, and connect to the cardano network. By default it will connect to the test network, you can run on other networks using the CARDANO_NETWORK environment variable, See the Environment variables section. If you want to run a stake pool, the block-producing container can take all the required steps to set up and register the stake pool.
This is an example on how to run your staking pool in a reasonably securely way, by keeping your cold-keys
and wallets
away from the online block-producing node. It is always a trade-off between security and convenience, but I find this method to be reasonably secure, if you can some precautions, as described in the below setup.
For this setup you will need 3 hosts.
host1
for running the relay node.
host2
host for running the block-producing node.
host3
host for generating and registering all the keys, addresses and certificates and storing the cold-keys for refreshing the KES keys and certificates. This can be a host you are running locally, for example a secure linux live boot, with all incoming traffic completely shut off. Warning: If you run on a Linux live boot, with no persistant storage, it is EXTREMELY important that you backup your staking directory containing all the private keys, before you shut it off, otherwise your wallets will be lost.
- Upload your stake-pool metadata json file (See example) to a host so it is accessible to the public. For example as a github gist.
- Start a relay node on
host1
and make it connect to the block-producing node onhost2
. See the relay node example. - Start a registration node on
host3
, with the--staking
and--create
arguments, and make it connect to the relay node onhost1
. See the registration node example. - Fund your payment address generated and displayed in Step 3 to finalize the registration.
- Wait for the registration node on
host3
to setup and register your pool. - Create Firewall rules for your block-producing node on
host2
to only accept incoming traffic from your relay node onhost1
. - Copy the
config/staking/pool-keys
directory from the registration node onhost3
to theconfig/staking/pool-keys
directory onhost2
. - Start a block-producing node on
host2
, with the--start
and--staking
arguments, and make it connect to the relay node onhost1
. See the block-producing node example.
To renew your KES keys and certificates you have to run the generate_operational_certificate
command in the registration container on host3
The status window in the block-producing container will tell you when you have to generate new keys.
- Start the command-line interface in the registration container, containing the
cold-keys
directory, onhost3
. Usingdocker exec -it main-registration bash
. - Run the
generate_operational_certificate
command and wait for it to complete. - Copy the
config/staking/pool-keys/
directory onhost3
to theconfig/staking/pool-keys/
directory onhost2
- Restart the block-producing container on
host2
.
Step 1. Run on host1
. See examples/main-relay1.sh
.
docker network create -d bridge cardano
docker run -it \
--restart=unless-stopped \
--network=cardano \
--name main-relay1 \
-e HOST_ADDR="0.0.0.0" \
-p 3000:3000 \
-p 12798:12798 \
-e NODE_PORT="3000" \
-e NODE_NAME="relay1" \
-e NODE_TOPOLOGY="<IP-address of block-producing node>:3000/1" \
-e NODE_RELAY="True" \
-e CARDANO_NETWORK="main" \
-e PROMETHEUS_PORT="12798" \
-v $PWD/config/:/config/ \
arradev/cardano-node:latest --start
Step 2. Run on host3
. See examples/main-registration.sh
.
docker network create -d bridge cardano
docker run -it --rm \
--name main-registration \
--network=cardano \
-e HOST_ADDR="0.0.0.0" \
-e NODE_PORT="3000" \
-e NODE_NAME="registration" \
-e NODE_TOPOLOGY="<IP-address of relay1 node>:3000/1" \
-e CARDANO_NETWORK="main" \
-e CREATE_STAKEPOOL="True" \
-e POOL_PLEDGE="100000000000" \
-e POOL_COST="340000000" \
-e POOL_MARGIN="0.05" \
-e METADATA_URL="<URL of metadata.json>" \
-v $PWD/config/:/config/ \
arradev/cardano-node:latest --create --staking
Step 5. Run on host2
. See examples/main-producing.sh
.
docker network create -d bridge cardano
docker run -it --rm \
--network=cardano \
--name main-producing \
-p 3000:3000 \
-p 12798:12798 \
-e HOST_ADDR="0.0.0.0" \
-e NODE_PORT="3000" \
-e NODE_NAME="block-producing" \
-e NODE_TOPOLOGY="<IP-address of relay1 node>:3000/1" \
-e CARDANO_NETWORK="main" \
-e PROMETHEUS_PORT="12798" \
-v $PWD/config/:/config/ \
arradev/cardano-node:latest --start --staking

This is an example on how to run your staking pool in a completely secure way, by only keeping your `cold-keys` and `wallets` on a completely offline node, and then transfer all relevant registration transactions and `pool-keys` to the online block-producing node. This requires a bit more steps than the reasonably secure method.
For this setup you will need 3 hosts.
`host1` for running the relay node.
`host2` host for running the block-producing node and submitting the registration transactions.
`host3` host for generating all the keys, addresses, certificates and transactions, and storing the cold-keys for refreshing the KES keys and certificates. This must be an completely offline host running locally.
1. Upload your stake-pool metadata json file ([See example](#metadata-example)) to a host so it is accessible to the public. For example as a [github gist](https://gist.github.com/).
2. Start a relay node on `host1` and make it connect to the block-producing node on `host2`.
3. Generate `protocol.json` on `host1` by running `get_protocol`.
4. Transfer the `protocol.json` from `host1` to the staking directory of `host3`.
5. Add the `metadata.json` file to `config/staking` directory the on `host3`
6. Start a cold-creation node `host3` using the `--create-cold` argument, and follow steps.
7. Fund your owners payment address(es) created on `host3`, make sure you send to the correct addresses.
8. Get UTXO and TXIX for funded owners payment address(es) by quering the address(es) on `host1` or `host2`.
9. Input the relevant UTXO and TXIX values when promted on `host3`.
10. Find the slot tip of the blockchain by running `get_slot` on `host1` or `host2`.
11. Input the slot tip on `host3` when prompted.
12. Create Firewall rules for your block-producing node on `host2` to only accept incoming traffic from your relay node on `host1`.
13. Upload staking-hot.tar.gz on `host2`
14. Start a block-producing node on `host2`, with the `--start`, `--staking` and `--register-cold` arguments, and make it connect to the relay node on `host1`.
15. Wait for the block-producing node on `host2` to register your pool and start staking.
See examples of the containers in `examples/best-practice/`.

**Warning:** These examples are ONLY for demonstration. The examples will run the nodes on the same server, using the `host` network, and connects to eachother using the localhost IP-address. This is not recommended. It is recommended to run the nodes on seperate servers and connect them using their public or local network IP-addresses, if they run within the same network. The idea is to keep the block-producing node completely locked off from anything other than the relay node. The block-producing node will also initialize and register the stake pool automatically, which is better to do on a seperate node, to keep the `cold-keys` directory and `wallets` secret key files (`wallets/*/*.skey`) completely away from the online nodes.1. Upload your stake-pool metadata json file ([See example](#metadata-example)) to a host so it is accessible to the public. For example as a [github gist](https://gist.github.com/).
2. Start a relay node and make it connect to the block-producing node. See the `examples/mc4-relay1.sh` example file.
3. Start a block-producing node with the `--start`, `--staking` and `--create` arguments, and make it connect to the relay node. See the `examples/mc4-producing.sh` example file.
4. Wait for the block-producing node to setup and register your pool.
5. Fund your payment address generated and displayed in Step 4 to finalize the registration.
The docker-compose file `examples/test/mc4-docker-compose.yaml` will run these 2 containers automatically. Use the command `docker-compose -f mc4-docker-compose.yaml up` to start them.
If you want to monitor your nodes using prometheus across different hosts, you can set the environment variable PROMETHEUS_HOST=0.0.0.0
. This makes the Prometheus service accessible to other hosts. So you can for example run a Prometheus+Grafana service on your relay node, scraping data from the block-producing and relay nodes.
If you do this, it is EXTREMELY important that you set up a Firewall rule ONLY allowing traffic from your relay nodes host on the Prometheus port, otherwise everyone will be able to monitor your node.
The examples/metadata.json
file is the file that holds metadata about your pool.
It looks like the following, and has to be upload to a host so it is accessible to the public via. an URL. You can for example upload it as a github gist.
{
"name": "Example Pool",
"description": "Cardano stakepool example",
"ticker": "TEST",
