Increase HEALTHCHECK start time for services that need to wait for host resolving during startup. In Docker Swarm mode the services listed below can get stuck in their start script, while they are waiting for other services become available. Now, with HEALTHCHECK enabled, docker does not resolve names of services that not pass HEALTHCHECK yet. Meaning that if one of the depenend services is not yet available, it will create a chain of failing services. The services below retry to resolve 100 time, with an average of 3.5 seconds. Hence, the --start-time flag is now set at 350 seconds. - dovecot (imap) - postfix (smtp) - rspamd (antispam) 2018-10-21 19:49:01 +02:00			`HEALTHCHECK --start-period=350s CMD echo QUIT\|nc localhost 25\|grep "220 .* ESMTP Postfix"`
