.SH SYNOPSIS
.PP
\f[B]docker_compose_update\f[R]
.SH DESCRIPTION
.PP
\f[B]docker_compose_update\f[R] is an utility to batch update
\f[I]docker-compose\f[R] deployments residing in sub folders of a
\f[B]base directory\f[R], e.g \f[I]/root/deployments/\f[R] having
different sub folders, each having a \f[I]docker-compose\f[R] deployment
in it.
.PP
By default, \f[B]docker_compose_update\f[R] tries to read from
\f[I]$HOME/.docker_compose_update.conf\f[R] and
\f[I]/etc/docker_compose_update.conf\f[R] for configuration.
It will exit with a non-zero exit code if it cannot find a proper
configuration file.
.PP
The following are at least required for the script to work:

.P
.PD
- \f[B]DOCKER_COMPOSE_UPDATE_BASEDIR=\[lq]/root/deployments\[rq]\f[R]
determines the \f[B]base directory\f[R] where all
\f[I]docker-compose\f[R] stacks are located in their own sub-folders.

.PD
- \f[B]DOCKER_COMPOSE_UPDATE_IGNORES=(\[lq]mailcow\[rq])\f[R] folder
names which will be ignored and not be updated, at least () is required.
.PD 0
.P
.PD
-
\f[B]DOCKER_COMPOSE_UPDATE_COMMANDS[aDirectoryName]=\[lq]./callFancyScriptInDirectory\[rq]\f[R]
to explicitly define update command for one sub folder
\f[I]aDirectoryName\f[R].
This is a map and defining different instructions for multiple locations
is possible.
Example: accessor has to match the folder,
e.g.\ \f[I]/aDirectoryName\f[R] will use command
\[lq]\f[I]./callFancyScriptInDirectory\[rq]\f[R] when changing directory
into it.
.PD 0
.P
.PD
- \f[B]DOCKER_COMPOSE_UPDATE_COMMAND=\[lq]sudo docker-compose down; sudo
docker-compose pull; sudo docker-compose up -d;\[rq]\f[R] determines the
default update command executed for each deployment.
.PD 0
.P
.PD
- \f[B]DOCKER_COMPOSE_UPDATE_FAIL_ON_UPDATE_ERROR=\[lq]false\[rq]\f[R]
determines if script fails if at least one update procedure failed.

You can copy this script to \f[I]/usr/local/bin\f[R] and use create a
custom \f[B]CONFIG_FILE\f[R] as user.
.SH EXAMPLE
.PP
Create a \f[I]$HOME/.docker_compose_update.conf\f[R] and necessary
configuration.
