Healthchecks.io Integration

[mark-monteiro]

Thought I'd share the configuration I'm using to integrate with healthchecks.io using the support for custom pre and post scripts.

You end up with a log of backups run, with a duration for each backup, and can set up notifications for when a backup fails to run at the expected time, or does not completed within the expected amount of time.

The scripts required and included below. You can re-use these scripts between multiple container instances, you just need to set a different HEALTHCHECK_URL environment variable value for each container.

Below is an example of the relevant parts you would need to add to a Docker Compose file (be sure to update HEALTHCHECK_URL)

  postgres-backup:
    image: tiredofit/db-backup:3.4.1
    volumes:
      - ./pre-script.sh:/assets/scripts/pre/pre-script.sh:ro
      - ./post-script.sh:/assets/scripts/post/post-script.sh:ro
    environment:
      - HEALTHCHECK_URL=https://hc-ping.com/00000000-0000-0000-0000-000000000000

Pre Script

#!/bin/sh

# Define command output to send to Healthchecks.io
# See: https://github.com/tiredofit/docker-db-backup#pre-backup
m=$(echo "'${1}' backup started on host '${2}' for db '${3}'. Filename: ${5}")

# Send update to healthchecks.io
# See: https://healthchecks.io/docs/measuring_script_run_time/
curl -fsS -m 30 --retry 5 --data-raw "$m" ${HEALTHCHECK_URL}/start

Post Script

#!/bin/sh

# Define command output to send to Healthchecks.io
# See: https://github.com/tiredofit/docker-db-backup#post-backup
m=$(echo "'${2}' backup completed on host '${3}' for db '${4}' after ${7} seconds. Filename: ${8} Size: ${9} MD5: ${10}")

# Send update to healthchecks.io
# See: https://healthchecks.io/docs/bash/
curl -fsS -m 30 --retry 5 --data-raw "$m" ${HEALTHCHECK_URL}/${1}

@mark-monteiro , could you please provide more details on this. is it working as expected or any blockers?

[mark-monteiro]

No blockers, it works as expected for me. I've been using this setup without issues for about 6 months now

Thank you.

@mark-monteiro Thanks for this! I was about to set this up myself. I used your scripts instead and they worked flawlessly.
