sendmail configuration is impossible inside a container about stackstorm-k8s HOT 6 CLOSED

I actually managed to get my own container build to work by changing sendmail.mc config with:

define(`SMART_HOST', `hostname_not_mx.tld')dnl
define(`nullclient', `hostname_not_mx.tld')dnl
dnl # LOCAL_DOMAIN(`localhost.localdomain')dnl

then running

buildah copy "$container" sendmail.mc /etc/mail/sendmail.mc
buildah run "$container" bash -c "bash /etc/mail/make"
buildah run "$container" bash -c "sendmail -bd"

but this isn't possible with the st2 container since the sendmail.mc config file needs to be changed and rebuilt

the most important setting was manually fixing /etc/hosts with xxx is the ip address below

xxx.xx.xx.xx    stackstorm-ha-st2actionrunner-7f4d87fdd-z6x5x.localhost stackstorm-ha-st2actionrunner-7f4d87fdd-z6x5x

of course manually editing this line is not a solution

In the end ssmtp is infinitly easier to setup with a config file

I agree, I made the same recommendation elsewhere, and it works well for me:

StackStorm/st2#6002

from stackstorm-k8s.

it turns out ssmtp does NOT work with piped input with To: in the input file. ssmtp requires a to address via command line

bash-4.4# cat mail | ssmtp
sendmail: No recipients supplied - mail will not be sent

so i ended up writing a new action instead of using sendmail and overriding the binary.

/usr/sbin/sendmail -t 

should work with the send_mail action
-t tells it to use the TO from the input file. Why they did that I have no idea. Probably some old rfc specification.

the stackstorm-email pack has a full python client that can be used in place of sendmail. # wont fix
