go-cat

Go Reference

go-cat is a Go command line tool which helps keep track of infrastructure across multiple clouds in a single git repository. It helps manage multiple components with their API endpoints, with the time they were last deployed on, and the commit SHA. This makes tracking huge infrastructure trees easier on the long run.

The project is in early alpha and under active development.

Installation ✨

cd cmd/go-cat
go build .
./go-cat --help

Usage 🤔

The go-cat upsert command mutates the json file and regenerates a new README.md with a markdown table containing information. API consumers can make use of infra.json to dynamically check from command line about the information about the latest deployment.

The go-cat add command adds infrastructure to queue, which can be then pushed to git repository using go-cat push. This feature is useful for batch updates to infrastructure, in one transaction.

Workflow 🔧

A general implementation workflow in an infrastructure repository would be

# do infrastructure changes 
terraform apply

terraform output -format=json > infra_info.json
 
go-cat upsert \
  --name company1-api1 --commit-sha=1c32fb0 \
  --cloud=GCP --cloud-project-id=my-awesome-project-41313 \
  --type=run.googleapis.com \
  --subsystem=company1 \
  --deployment-link=$(cat infra_info.json | jq .deployment_link) \
  --git.url=https://gitlab.com/something/xxx.git \
  --git.username=username \
  --git.password=mysupersecretpassword

The git.url, git.username and git.password can also be configured using environment variables GO_CAT_GIT_URL, GO_CAT_GIT_USERNAME, GO_CAT_GIT_PASSWORD respectively.

To remove any component from the infrastructure catalog, go-cat now supports a remove subcommand, which helps us remove components using all the power of regex.

# to remove only one component
go-cat remove --id 'gcp/project1/subsystem/component'
# this will remove component named 'component', belonging to 'subsystem', in project 'project1' deployed on GCP.

# to remove all components, subsystems, projects of a cloud
go-cat remove --id 'gcp/*'

# to remove all components which are called 'api' across all clouds
go-cat remove --id '.*/api'

# to remove a specific subsystem across all cloud projects
go-cat remove --id 'gcp/.*/subsystem/component'
