loglog

This is a simple ZIO based application that collects concurrent online viewership metrics from Slovenian national broadcaster and its RTV 356 online services.

Configuration

export LOGLOG_ENV="development"

export INFLUXDB_URL="http://0.0.0.0:8086"
export INFLUXDB_TOKEN="<required>"
export INFLUXDB_ORG="<required>"
export INFLUXDB_BUCKET="<required>"
export PATCH_API_URL=http://localhost:7070

Development

./bin/loglog-dev.sh up -d --remove-orphans
sbt ~reStart # On host
sbt "~compile;docker:publishLocal;reStartContainer" # Via Docker

Deployment

Release a new version with the following SBT command.

sbt "release release-version 0.0.1 next-version 0.0.2"

Deploy to production with sbt and ansible playbook with

sbt "docker:publish;deploy"

Experimentation with networking

To demonstrate the service resiliency to networking exceptions; the following example can be used to inject networking " delay" into "gateway" nginx proxy container. This will cause the service to fail and yet proceed to operate.

./bin/loglog-dev.sh exec gateway tc qdisc add dev eth0 root netem delay 10s

To remote the delay from the container via tc you can use the following set of commands

./bin/loglog-dev.sh exec gateway tc qdisc del root dev eth0
