• Run docker-compose up -d

• Get metrics at curl localhost:8880/metrics

ENVs

• CURL1_CMD - curl command to be executed from time to time. Ex.: curl --fail https://yahoo.com. required
• CURL1_NAME - label name on metrics for this job. defaults to job number (curl-3, curl-1)
• CURL1_SLEEP - sleep time between calls in seconds. defaults to 5
• CURL1_PARALLEL - how many curl tasks to run in parallel. defaults to 1

You can add multiple instructions for multiple curls running in parallel by incrementing numbers in labels. Ex: CURL1_CMD, CURL2_CMD, CURL3_CMD...
