colon (<quote>:</quote>) and a syslog log level (e.g, REJECT:info or

ACCEPT:debugging). This causes the packet to be logged at the

specified level. You may also specify ULOG (must be in upper case)

<title>Shorewall 5.0.5 and Earlier</title>

<para>Both Docker and Shorewall assume that they 'own' the iptables
|
||||
configuration. This leads to problems when Shorewall is restarted or
|
||||
reloaded, because it drops all of the rules added by Docker. Fortunately,
|
||||
the extensibility features in Shorewall allow users to <ulink

these operations and restoring them afterwards.</para>

<title>Shorewall 5.0.6 and Later</title>
|
||||
|
||||
<para>Beginning with Shorewall 5.0.6, Shorewall has native support for
|
||||
simple Docker configurations. This support is enabled by setting
|
||||
DOCKER=Yes in shorewall.conf. With this setting, the generated script
|
||||
saves the Docker-created ruleset before executing a
|
||||
<command>stop</command>, <command>start</command>,
|
||||
<command>restart</command> or <command>reload</command> operation and
|
||||
restores those rules along with the Shorewall-generated ruleset.</para>
|
||||
|
||||
<para>This support assumes that the default Docker bridge (docker0) is
|
||||
being used. It is recommended that this bridge be defined to Shorewall in
|
||||
<ulink
|
||||
url="manpages/shorewall-interfaces.html">shorewall-interfaces(8)</ulink>.
|
||||
As shown below, you can control inter-container communication using the
|
||||
<option>bridge</option> and <option>routeback</option> options. If docker0
|
||||
is not defined to Shorewall, then Shorewall will save and restore the
|
||||
FORWARD chain rules involving that interface.</para>
