URL shortener microservice using `Go kit`_, Docker_, and `Amazon EKS`_.
Development Environment:
- `Ubuntu 20.04`_
- `Go 1.17`_
Description
+++++++++++
See `Assignment `_.
Usage
+++++
First install ``Docker Engine`` and `Docker Compose`_.
To run the micro-service in Docker_ environment:
.. code-block:: bash
$ sudo docker-compose up --build
To create short URL:
.. code-block:: bash
$ curl -XPOST -d'{"url":"https://github.com/siongui/go-kit-url-shortener-micro-service"}' localhost:8080/create
{"short_url":"20wogJaCuRtH0U5p60LvjZoVwsz"}
To recover the original URL:
.. code-block:: bash
$ curl -XGET localhost:8080/20wogJaCuRtH0U5p60LvjZoVwsz
{"url":"https://github.com/siongui/go-kit-url-shortener-micro-service"}
If you HTTP GET some URL that does not exist, you will get:
.. code-block:: bash
$ curl -XGET localhost:8080/20wogJaCuRtH0U5p
{"url":"","err":"sql: no rows in result set"}
To see metrics of the the micro-service:
.. code-block:: bash
$ curl -XGET localhost:8080/metrics
Database Configuration
++++++++++++++++++++++
The application will determine which database to use according to environment
variables. The application first check if the following environment variables
are set:
- POSTGRES_USER
- POSTGRES_PASSWORD
- POSTGRES_HOST
- POSTGRES_PORT
- POSTGRES_DB
If they are set, The application will try to connect to PostgresSQL. If
connection failure, the application will panic. If the *POSTGRES* env are not
set, the application will then check the following environment variable:
- SQLITE_DSN
If it is set, the application will try to connect to SQLite, panic if connection
failure.
If all above environment variables are not set, the application will use SQLite
with ``file::memory:?cache=shared`` DSN. See `getds.go `_ for details.
