Add custom build of coredns 2018-01-30 22:26:44 +00:00
Rebuild to use crond and pre-compiled binary The build process of the binary patched with the cron runner was too instable as coredns is not properly vendoring their dependencies. This way the binary is stable (provided by coredns) and the cron is taken over by alpine crond. Signed-off-by: Knut Ahlers <knut@ahlers.me> 2018-03-04 12:41:25 +00:00			`RUN set -ex \`
