Counter

Counter is a web application that increases the value of a counter every time it is clicked.

Configuration

Mount Point

The service can be mounted with a specific mount point (prefix path). This path can be forwarded from the load balancer as the header X-Mount-Point or it can be given as a environment variable, COUNTER_MOUNT_POINT, when starting the container.

Stores

The application supports four different stores, they are configured with environment variables.

Memory

This is the default store. It stores the counter in memory and is reset on every restart.

# With binary
$ counter-linux

# With docker
$ docker run -d andersjanmyr/counter

Redis

Stores the counter in Redis. It is configured by setting the environment variable REDIS_URL to a Redis endpoint such as localhost:6379

# With binary and local Redis
$ REDIS_URL=localhost:6379 counter-linux

# With docker and local Redis
$ docker run -d -e REDIS_URL=localhost:6379 andersjanmyr/counter

# Or with link, assuming a Redis container named redis is running
docker run -d --link redis -e REDIS_URL=redis:6379 andersjanmyr/counter

Mongo

Stores the counter in Mongo. It is configured by setting the environment variable MONGO_URL to a Mongo endpoint such as localhost:27017

# With binary and local Mongo
$ MONGO_URL=localhost:27017 counter-linux

# With docker and local Mongo
docker run -d -e MONGO_URL=localhost:27017 andersjanmyr/counter

# Or with link, assuming a Mongo container named mongo is running
docker run -d --link mongo -e MONGO_URL=mongo:27017 andersjanmyr/counter

Postgres

# With binary and local Postgres
$ POSTGRES_URL=postgres://localhost counter-linux

# With docker and local Postgres
docker run -d -e POSTGRES_URL=postgres://localhost andersjanmyr/counter

# Or with link, assuming a Postgres container named postgres is running
