clear acl

Delete all entries from an ACL expression or file.

Description

An ACL is split into four parts:

  • a name for the ACL, which you choose

  • a fetch to collect information from the client's session

  • optional flags

  • a value to match against

In the example below, we mark these parts:

frontend www
   bind :80
   #   name       fetch  flags       value
   acl static_url  path   -i -m beg   /images/ /scripts/

Here, there is initially two values, /images/ and /scripts/. Use clear acl to delete all values.

You can also store values in a file and then reference that file in an acl statement by using the -f /path/to/file flag. Use the clear acl command to delete all values from the file. Note that this only removes it from HAProxy Enterprise's runtime memory and not to the file on disk.

Examples

Use clear acl to remove the values /images/ and /scripts/. You can specify the acl file by path or ID. Here we use the ID, which you can get from show acl.

$ echo "clear acl #0" | \
   sudo socat stdio unix-connect:/var/run/hapee-2.2/hapee-lb.sock

In the next example, we remove all values from the ACL file /etc/hapee-2.2/paths.acl:

$ echo "clear acl /etc/hapee-2.2/paths.acl" | \
   sudo socat stdio unix-connect:/var/run/hapee-2.2/hapee-lb.sock
