Docker setup

This document describes how to run Lisk Core as a Docker image-based container. Lisk Core version 4 does not have any external dependencies and hence does not require using docker-compose.


Hardware requirements

The following system requirements are recommended:

  • Machines with a minimum of 4 GB RAM for the Mainnet.

  • Machines with a minimum of 2 GB RAM for the Testnet.

  • Machines with a minimum of 40 GB HDD[1].

Create a new user

To run and manage a Lisk Core node in the future, please create a separate lisk user as described below:

  • Ubuntu

  • MacOS

The lisk user itself does not need any sudo rights to run the Lisk Core.

sudo adduser lisk (1)
1 Create a new user.

It is not necessarily required to set up a lisk user, especially when you are running a local instance for development purposes.

However, if it is required then it is recommended to create the user using the MacOS GUI.

Install Docker

To run Lisk Core in Docker, firstly it is necessary to install the Docker engine. Determine if your platform can run Docker as described below.

Please refer to the Docker installation page.

  • Ubuntu

  • MacOS

  • Windows

Please refer to the Docker installation for ubuntu.

Configure Docker, in order that it can be run without sudo rights: linux post install.

Install make using your package manager. For example, use apt-get if running Ubuntu as shown below:

sudo apt-get install curl make

Please refer to Docker installation for Mac. Install make using XCode.

Lisk Core download

git clone (1)
cd lisk-core/docker                  (2)
git checkout v4.0.0 -b v4.0.0 (3)
1 Clone the repository.
2 Navigate into the lisk-core root folder.
3 Check out the latest release tag.
Please check for the latest release in the Lisk Core releases list.



It is also possible to use podman instead of docker by simply replacing the occurrences of docker with podman, in the following examples or alternatively by creating an alias with alias docker=podman.

Create a "lisk-core" container:

  • Mainnet

  • Testnet

  • Devnet

docker run --volume lisk-data:/home/lisk/.lisk \
           --publish 7887:7887 \
           --name lisk-core \
           lisk/core:4.0.0 \
           start --network=mainnet

The default log levels for Mainnet are:

"logger": {
    "fileLogLevel": "error",
    "LogLevel": "none"

So if you start the node, it won’t show any logs in the console. This is the recommended setting for reducing the number of logs for a running node. However, to verify that the node started correctly, update the log levels in the config to info or lower.

Alternatively, start the node with the following flag:

start --network mainnet --console-log=info
docker run --volume lisk-data:/home/lisk/.lisk \
           --publish 7887:7887 \
           --name lisk-core \
           lisk/core:4.0.0 \
           start --network=testnet
docker run --volume lisk-data:/home/lisk/.lisk \
           --publish 7887:7887 \
           --name lisk-core \
           lisk/core:4.0.0 \
           start --network=devnet
The passphrase for the genesis account(s) can be found here in the Lisk Core GitHub repository under the following path: config/devnet/passphrase.json.


Further parameters can be passed after --network, for example, as shown below:

docker run --volume lisk-data:/home/lisk/.lisk \
           --publish 7667:7667 \
           --publish \
           --name lisk-core \
           lisk/core:4.0.0 \
           start --network=testnet --api-ws --api-http --log=debug

Environment variables can be set with --env:

docker run --volume lisk-data:/home/lisk/.lisk \
           --publish 7667:7667 \
           --env LISK_CONSOLE_LOG_LEVEL=debug \
           --name lisk-core \
           lisk/core:4.0.0 \
           start --network=mainnet

Import blockchain snapshot

docker run --volume lisk-data:/home/lisk/.lisk -it --rm lisk/core:4.0.0 blockchain download --network=betanet --output=/home/lisk/.lisk/tmp/
docker run --volume lisk-data:/home/lisk/.lisk -it --rm lisk/core:4.0.0 blockchain import /home/lisk/.lisk/tmp/blockchain.db.tar.gz
docker run --volume lisk-data:/home/lisk/.lisk -it --rm --entrypoint rm lisk/core:4.0.0 -f /home/lisk/.lisk/tmp/blockchain.db.tar.gz
docker start lisk-core
docker logs -f lisk-core

1. These recommendations are derived from the log level settings, in the event that the user needs to increase storage to prevent limited memory access and potential memory-related problems with a node. Furthermore, as more transactions are processed and added to the blockchain, the size of the blockchain increases over time and this directly affects the HDD storage requirements for a blockchain node. Hence, adhering to the above listed requirements is highly recommended.
