<% %> in template files

Chef Infra (archive)
1

I have a line I need to add to my rsyslog.conf.erb template, but chef
doesn’t seem to like it because it contains the characters <% and %> and
there’s not any ruby between them.

For example, I added this line to my template (it needs to be added to the
rsyslog.conf on all my nodes):

$template GRAYLOG2,"<%PRI%>1 %timegenerated:::date-rfc3339% %HOSTNAME%
%syslogtag% - %APP-NAME%: %msg:::drop-last-lf%\n"

but chef seems to be getting confused by <%PRI%>

What do people suggest to work around this? Is there some way I can escape
those characters in a template or tell chef to treat them literally and not
as a ruby command or variable marker?

That worked perfectly. <%%PRI%> in the template renders <%PRI%> in the
chef-generated file.

Thanks again!
