Todo Deployment App

This is a simple Todo list application which connects to a Postgres database or cluster, intended to assist in a Morpheus Deployments training session.

Based on the example found in here.

Modified so that the external assets are part of the binary to simplify deployment.

Setup

Grab a release from the releases page, download and extract the binary.

There are two releases (v1.0.0 & v2.0.0) which have visual differences in the UI to demonstrate deployment versioning.

Create a Morpheus deployment with the binary.

Create a Morpheus script file config.env which contains the single required environment variable PG_HOST. All other connection info is hardcoded in the app for simplicity, but may be overridden here. The location of this file is passed as a command line flag.

# POSTGRES CONFIG
PG_HOST=54.237.172.XXX

# OPTIONAL TO OVERRIDE DEFAULTS
#PG_PORT=               # default is 5432
#PG_USER=               # default is postgres
#PG_PASSWORD=           # default is Password123?
#PG_DATABASE=           # default is todos
#APP_SERVER_PORT=       # default is 8090

Run

Run the application like this:

./todo -config={absolute path to config.env}

Optionally nohup the call or set up as a service so tasks can be created to start and stop the app in Morpheus.
