Endtoend Service

This is the Endtoend service which performs end to end testing in live to ensure uptime.

What does it do?

There is a cron job which fires the check every X minutes. The check will download micro via the m3o install script (https://install.m3o.com/micro) and run micro signup. This satisfies the requirement to run what the user runs.

The email address used is from https://www.cloudmailin.com/ that allows us to receive emails on a webhook. This means we can pull out the OTP for email verification.

The result of the check is recorded in the store and can be queried via the check endpoint. This can be called externally by uptime robot and the result will indicate whether the last check was successful and recent (within 5 mins).

Setup

To setup this service for a new environment you should

Setup an email address

See https://www.cloudmailin.com/ to sign up for a new email.

You should set it up to post email in JSON normalized format and set the target URL to https://api.<domain>/endtoend/mailin

Setup the config

You need to setup the email address that you've just signed up for

micro config set micro.endtoend.email <email address from previous step>

Setup auth rules

To enable external monitoring we need to allow public access to /endtoend/check through the API

micro auth create rule --resource="service:endtoend:Endtoend.Check" endtoendcheck
micro auth create rule --resource="service:endtoend:Endtoend.Mailin" endtoendmail

Deploy

micro run m3o.dev/api/endtoend

Setup your external monitor

Setup your external monitor (uptime robot, etc) to ping https://api.<domain>/endtoend/check

Manual checking

Checks can be triggered manually by hitting the RunCheck endpoint

micro endtoend RunCheck

and you can check the logs or the usual alert channels for success/failure.
