Contanerized Lotus devnet using a mocked sectorbuilder

Lotus Devnet

Runs a Lotus Devnet using a mocked sectorbuilder which can be accesed as a real Lotus node through the API. The devnet code is always tried to be update with Lotus latest master tag.

Run

You can run the devnet with:

go run main.go

The devnet supports the following configuration:

• -speed: Time in milliseconds that blocks are mined. Default is 100ms.
• -numminers: Number of miners. Default is 1. (Note: higher values is an experimental feature)
• -bigsectors: Miners will use 512Gib sector sizes. Default is true, if set to false miners will use 2Kib sectors
• -ipfsaddr: IPFS multiaddr to allow the client be connected to an IPFS node as a blockstorage.

All flags can be specified by environment variables using the TEXLOTUSDEVNET_ prefix. e.g: TEXLOTUSDEVNET_SPEED=1000

Docker

The Lotus Devnet was originally thought for integration tests in CI pipelines.

Build locally

You can build the Docker image by running docker build ..

Public images

A public Docker image is hosted in DockerHub on every master commit. Refer to textile/lotus-devnet.

For example, running a Lotus Devnet with 1.5s block generation speed:

docker run -e TEXLOTUSDEVNET_SPEED=1500 textile/lotus-devnet
