GOingToREST

GOingToREST is a simple 3-app system built for me to learn about communicating between different services.

• poster/poster.go
  • Listens to POST requests
  • Redirects data from POSTs to Rabbitmq
• saver/saver.go
  • Consumes Rabbitmq queue
  • Saves incoming data to Redis
• explorer/explorer.go
  • Listens to GET requests @ /size
  • Returns the count of all keys in Redis
• user/user.go
  • Struct User with some sample fields like id, name, surname, and age.

For debugging/testing purposes, in scripts/ there is post_curl.sh which sends random POSTs of correct form (remark: jq required)

Requirements

• Docker bridge

$ docker network create <network-name>

• Redis (@ port 6379 & name=redis by default, can be changed in config.yaml)
• Rabbitmq (@ port 5672 & name=rabbitmq by default, can be changed in config.yaml)

Usage

In order to build docker images for apps in poster/, saver/, and explorer/ run

$ # Let <name> = poster, etc.
$ docker build -t <name> .

To run:

$ docker run --rm -it --name <name> --network <network-name> -v <path to config file>:<$CONFIG_PATH><$CONFIG_NAME>.<$CONFIG_TYPE> -p <ports> <name>
