How to run a Cardano Node with Docker⚓︎
With this quick guide you will be able to run a cardano node in seconds and also have the powerfull Koios SPO scripts built-in.
How to operate interactively within the container⚓︎
Once executed the container as a deamon with attached tty you are then able to enter the container by using the flag
While if you have a hook within the container console, use the following command (change
CN with your container name):
docker exec -it CN bash
This command will bring you within the container bash env ready to use the Koios tools.
Docker flags explained⚓︎
"docker build" options explained: -t : option is to "tag" the image you can name the image as you prefer as long as you maintain the references between dockerfiles. "docker run" options explained: -d : for detach the container -i : interactive enabled -t : terminal session enabled -e : set an Env Variable -p : set exposed ports (by default if not specified the ports will be reachable only internally) --hostname : Container's hostname --name : Container's name
Custom container with your own cfg⚓︎
docker run --init -itd -name Relay # Optional (recommended for quick access): set a name for your newly created container. -p 9000:6000 # Optional: to expose the internal container's port (6000) to the host <IP> port 9000 -e NETWORK=mainnet # Mandatory: mainnet / preprod / guild-mainnet / guild --security-opt=no-new-privileges # Option to prevent privilege escalations -v <YourNetPath>:/opt/cardano/cnode/sockets # Optional: useful to share the node socket with other containers -v <YourCfgPath>:/opt/cardano/cnode/priv # Optional: if used has to contain all the sensitive keys needed to run a node as core -v <YourDBbk>:/opt/cardano/cnode/db # Optional: if not set a fresh DB will be downloaded from scratch cardanocommunity/cardano-node:latest # Mandatory: image to run
To be able to use the CNTools encryption key feature you need to manually change in "cntools.config" ENABLE_CHATTR to "true" and not use the
--security-opt=no-new-privileges docker run option.
