FireHydrant CLI (fhcli)

This client allows you to submit free-form change events to the FireHydrant API from your infrastructure. When incidents are opened on FireHydrant, recent change events will be automatically suggested to the responding team.

Example Events

  • Deploys
  • Docker image builds
  • Terraform runs
  • Cronjobs

Installation

GitHub release (latest by date)

New tags automatically create a release using goreleaser and can be found on the releases page of this repository.

Our releases follow the standard format of fhcli_{version}_{os}_{arch}.tar.gz - To grab the latest on your CI environment (as an example), you can run something like:

$ cd /usr/local/bin
$ wget -c https://github.com/firehydrant/fhcli/releases/latest/download/fhcli_0.0.14_linux_arm64.tar.gz -O - | tar -xz
$ fhcli --version

Environment Variables

Configuration file

We also accept a YAML configuration file, specified with -config or passed in as an environment variable. If none is specified, the following paths will be checked in order for a configuration file.

  • /etc/firehydrant.cfg
  • $HOME/firehydrant.cfg
  • /tmp/firehydrant.cfg

Examples

The following examples assume that FH_API_KEY is set in your environment.

fhcli event --environment "production" "hourly reconciliation task"
fhcli event --environment "staging" --identities git=git@github.com/firehydrant/myrepo:a0b0c0d0 "CI build succeeded"
fhcli execute --environment "staging" --identities revision=a0a0a0 -- docker build .

To configure firehydrant and write a config file (defaults to /tmp/firehydrant.cfg) for subsequent invocations of the tool:

fhcli --config /etc/firehydrant.cfg --apiKey fhb-a0b010 --environment=production --service=monolith init
