# Welcome to Zammad
|
|
|
|
Zammad is a web based open source helpdesk/ticket system with many features
|
|
to manage customer communication via several channels like telephone, facebook,
|
|
twitter, chat and emails. It is distributed under the GNU AFFERO General Public
|
|
License (AGPL). Do you receive many emails and want to answer them with a team of agents?
|
|
You're going to love Zammad!
|
|
|
|
## Use case for this repository
|
|
|
|
This repository is meant to be the starting point for somebody who likes to use dockerized multi-container Zammad in production.
|
|
|
|
## Getting started with zammad-docker-compose
|
|
|
|

## Using a reverse proxy
|
|
|
|
In environments with more then one web applications it is necessary to use a reverse proxy to route connections to port 80 and 443 to the right application.
|
|
To run Zammad behind a reverse proxy, we provide `docker-compose.proxy-example.yml` as a starting point.
|
|
|
|
1. Copy `./.examples/proxy/docker-compose.proxy-example.yml` to your own configuration, e.g. `./docker-compose.prod.yml`
|
|
`cp ./.examples/proxy/docker-compose.proxy-example.yml ./docker-compose.prod.yml`
|
|
2. Modify the environment variable `VIRTUAL_HOST` and the name of the external network in `./docker-compose.prod.yml` to fit your environment.
|
|
3. Run docker-composer commands with the default and your configuration, e.g. `docker-compose -f docker-compose.yml -f docker-compose.prod.yml up -d`
|
|
|
|
See `.examples/proxy/docker-compose.yml` for an example proxy project.
|
|
|
|
Like this, you can add your `docker-compose.prod.yml` to a branch of your Git repository and stay up to date by merging changes to your branch.
|
|
|
|
## Using Rancher
|
|
|
|
```console
|
|
RANCHER_URL=http://RANCHER_HOST:8080 rancher-compose --env-file=.env up
|
|
```
|
|
|
|
## Running without Elasticsearch
|
|
|
|
Elasticsearch is an optional, but strongly recommended dependency for Zammad. More details can be found in the [documentation](https://docs.zammad.org/en/latest/prerequisites/software.html#elasticsearch-optional). There are however certain scenarios when running without Elasticsearch may be desired, e.g. for very small teams, for teams with limited budget or as a temporary solution for an unplanned Elasticsearch downtime or planned cluster upgrade.
|
|
|
|
Elasticsearch is enabled by default in the example `docker-compose.yml` file. It is also by default required to run the "zammad-init" command. Disabling Elasticsearch is possible by setting a special environment variable: `ELASTICSEARCH_ENABLED=false` for the `zammad-init` container and removing all references to Elasticsearch everywhere else: the `zammad-elasticsearch` container, it's volume and links to it.
|
|
|
|
## Upgrading
|
|
|
|
### From =< 3.3.0-12
|
|
|
|
We've updated the Elasticsearch image from 5.6 to 7.6.
|
|
As there is no direct upgrade path we have to delete all Elasticsearch indices and rebuild them.
|
|
This will depend on the name of your docker container and volume, which depends on the checkout directory (`zammad-docker-compose` by default):
|
|
|
|
```console
|
|
docker-compose stop
|
|
docker container rm zammad-docker-compose_zammad-elasticsearch_1
|
|
docker volume rm zammad-docker-compose_elasticsearch-data
|
|
docker-compose up --no-recreate
|
|
```
|
|
|
|
To workaround the [changes in the PostgreSQL 9.6 container](https://github.com/docker-library/postgres/commit/f1bc8782e7e57cc403d0b32c0e24599535859f76) do the following:
|
|
|
|
```console
|
|
docker-compose start
|
|
docker exec -it zammaddockercompose_zammad-postgresql_1 bash
|
|
psql --username postgres --dbname zammad_production
|
|
CREATE USER zammad;
|
|
ALTER USER zammad WITH PASSWORD 'zammad';
|
|
ALTER USER zammad WITH SUPERUSER CREATEDB;
|
|
```
|
|
|
|
### From =< 3.6.0-65
|
|
|
|
To be able to run Zammad container with an unprivileged user we had to change the port Nginx uses from 80 to 8080, so Zammad needs to be accessed via <http://localhost:8080> instead of <http://localhost> now!
|
|
|
|
This change will also affect you, if you use a reverse proxy, like Traefik or Haproxy, in front of Zammad as your reverse proxy configuration needs to be adapted to point to port 8080 now.
|
|
|
|
### From =< 4.0.0 to 5.0.0
|
|
|
|
Memchached config changed. If you use the old env vars `MEMCACHED_HOST` & `MEMCACHED_PORT` adapt to `MEMCACHE_SERVERS`.
|
|
Redis is a dependency for the Websocket server now.
