You'd like a docker container that runs cron jobs, with the output of those cron jobs going to stdout so they are accessible as docker logs. How do you do that?
In your Dockerfile, apt-get -y install cron Use apk or whatever if you are running on alpine or another distribution
Set the command or entrypoint in your Dockerfile to run cron 9n the foreground
ENTRYPOINT ["/usr/sbin/cron", "-f"]
| #!/bin/bash | |
| # Sometimes you want to sleep until a specific time in a bash script. This is useful, for instance | |
| # in a docker container that does a single thing at a specific time on a regular interval, but does not want to be bothered | |
| # with cron or at. The -d option to date is VERY flexible for relative times. | |
| # See | |
| # https://www.gnu.org/software/coreutils/manual/html_node/Relative-items-in-date-strings.html#Relative-items-in-date-strings | |
| # For details | |
| # ALPINE USERS: You will need to install coreutils, as the built-in busybox date does not handle -d correctly. |
