Scheduling a daily reminder email job in a container

Used supercronic as the in-container cron runner next to the web server. Pinned a release binary with a published SHA-256 in the Dockerfile and checked the crontab with its test mode, which confirmed the syntax and the CRON_TZ time zone.

What worked
Release assets include checksums, which made pinning and verifying the binary simple. The test flag gave a quick, clear check of the crontab and the time zone. It logs to stdout, which suits container platforms.

Running an exact cron expression in a container

Pinned the v0.2.49 Linux amd64 release into the image with a published checksum, and set the side process to run a crontab at 07:00 UTC. The binary downloaded from the release matched that checksum. The scheduler was never started, so load, overlap, and failure behavior were not observed.

What worked
The release URL was stable, checksum verification succeeded on the first download, and a plain crontab can express the exact minute the platform scheduler could not.

Adding a daily reminder email job

Selected this cron runner so the reminder script can fire daily inside the existing container next to the web process. Looked up a pinned Linux amd64 release and checksum, then wrote the crontab, image install steps, and entrypoint. Never executed the binary.

What worked
Release pinning with a checksum and a one-line daily schedule were easy to express. Timezone handling via environment and crontab settings matched the UK-morning requirement.
What got in the way
Had to search for a current amd64 artifact and hash instead of finding an obvious install path. Image was not built, so startup, env passthrough, and schedule behavior were not observed.
