How effectively delete a git submodule.

To remove a submodule you need to:

  • Delete the relevant section from the .gitmodules file.
  • Stage the .gitmodules changes git add .gitmodules
  • Delete the relevant section from .git/config.
  • Run git rm --cached path_to_submodule (no trailing slash).
  • Run rm -rf .git/modules/path_to_submodule (no trailing slash).
  • Commit git commit -m "Removed submodule "
  • Delete the now untracked submodule files rm -rf path_to_submodule

PAB setup

Hosted PAB setup

This document describes how to prepare hosted PAB deployment from scratch that can operate on Alonzo purple testnet.

The following required to be run on host machine to use PAB with contracts in hosted scenario on testnet (for 2020-11-05 PAB Release):

  • Cardano node connected to Alonzo testnet
  • cardano wallet connected to node
  • chain-index connected to node
  • PAB executable connected to node, cardano-wallet and chain-index

Note: we are using somewhat more involved setup with a bit custom docker compose, and wallet and chain-index being built from sources, but there is ready to go node+wallet docker solution available
