I’ve created this acl:
acl in_maintenance always_false -u 1
And use it like this (yes, I know there are other ways to do it, there’s a reason for this):
use_backend sorry if in_maintenance
But can’t figure out how to change the acl to the value “always_true” using socat. I can see the acl when I run “show acl”:
1 () acl ‘always_false’ file ‘/etc/haproxy/haproxy.cfg’ line 74
But any attempt to use “add acl” or “del acl” throws an error or says Done, but doesn’t change the backend. For example:
echo “add acl #1 always_true” | socat tcp-connect:192.168.2.107:9999 stdio
Hitting the url doen’t take you to the “sorry” backend.
Likewise, attempting to delete:
echo “del acl #1 always_false” | socat tcp-connect:192.168.2.107:9999 stdio
Key not found.
Obviously, I don’t understand how to use this.
To put it simply, how do I change the acl from “always_false” to “always_true” and back?
