Actions

Required binaries. Install these on the host before relying on the pack — an action that calls a missing one fails at run time.

nc

Install

emisar pack install validates the pack and verifies its content hash before copying it into /etc/emisar/packs. The --hash below pins the install to the exact bytes on this page — a tampered copy is rejected. After install, reload the runner; it re-reads the catalog and advertises every action.

content hash: sha256:5081146ff6ad83ef059ea0db57bb1fab2ef652b70d640d4515c4769e45736aa8

on the runner host

sudo emisar pack install zookeeper \
  --hash sha256:5081146ff6ad83ef059ea0db57bb1fab2ef652b70d640d4515c4769e45736aa8 \
  --dest /etc/emisar/packs

# Reload so the runner re-reads the catalog:
sudo systemctl reload emisar
