# Introduction
Dockerfile to build an [ejabberd](https://www.ejabberd.im/) container image.
Docker Tag Names are based on ejabberd versions in git [tags][]. The image tag `:latest` is based on the master branch.
[tags]: https://github.com/rroemhild/ejabberd/tags
# Quick Start
You can start of with the following container:
```bash
docker run -d \
--name "ejabberd" \
-p 5222:5222 \
-p 5269:5269 \
-p 5280:5280 \
-h 'xmpp.example.de' \
-e "XMPP_DOMAIN=example.de" \
-e "ERLANG_NODE=nodename" \
-e "EJABBERD_ADMINS=admin@example.de admin2@example.de" \
-e "EJABBERD_USERS=admin@example.de:password1234 admin2@example.de" \
-e "TZ=Europe/Berlin" \
rroemhild/ejabberd
```
# Usage
## Persistence
For storage of the application data, you can mount volumes at
* `/opt/ejabberd/ssl`
* `/opt/ejabberd/backup`
* `/opt/ejabberd/upload`
* `/opt/ejabberd/database`
or use a data container
```bash
docker create --name ejabberd-data rroemhild/ejabberd-data
docker run -d --name ejabberd --volumes-from processone-data rroemhild/ejabberd
```
## SSL Certificates
TLS is enabled by default and the run script will auto-generate two snake-oil certificates during boot if you don't provide your SSL certificates.
To use your own certificates, there are two options.
1. Mount the volume `/opt/ejabberd/ssl` to a local directory with the `.pem` files:
* /tmp/ssl/host.pem (SERVER_HOSTNAME)
* /tmp/ssl/xmpp_domain.pem (XMPP_DOMAIN)
Make sure that the certificate and private key are in one `.pem` file. If one file is missing it will be auto-generated. I.e. you can provide your certificate for your **XMMP_DOMAIN** and use a snake-oil certificate for the `SERVER_HOSTNAME`.
2. Specify the certificates via environment variables: **EJABBERD_SSLCERT_HOST** and **EJABBERD_SSLCERT_EXAMPLE_COM**. For the
domain certificates, make sure you match the domain names given in **XMPP_DOMAIN** and replace dots and dashes with underscore.
## Base Image
Build your own ejabberd container image and add your config templates, certificates or [extend](#cluster-example) it for your needs.
```
FROM rroemhild/ejabberd
ADD ./ejabberd.yml.tpl /opt/ejabberd/conf/ejabberd.yml.tpl
ADD ./ejabberdctl.cfg.tpl /opt/ejabberd/conf/ejabberdctl.cfg.tpl
ADD ./example.com.pem /opt/ejabberd/ssl/example.com.pem
```
If you need root privileges switch to `USER root` and go back to `USER ejabberd` when you're done.
# Ejabberd Configuration
You can additionally provide extra runtime configuration in a downstream image by replacing the config template `ejabberd.yml.tpl` with one based on this image's template and include extra interpolation of environment variables. The template is parsed by Jinja2 with the runtime environment (equivalent to Python's `os.environ` available as `env`).
## Served Hostnames
By default the container will serve the XMPP domain `localhost`. In order to serve a different domain at runtime, provide the **XMPP_DOMAIN** variable with a domain name. You can add more domains separated with whitespace.
```
XMPP_DOMAIN=example.ninja xyz.io test.com
```
## Authentication
Authentication methods can be set with the **EJABBERD_AUTH_METHOD** environment variable. The default authentication mode is `internal`.
Supported authentication methods:
* anonymous
* internal
* external
* ldap
Internal and anonymous authentication example:
```
EJABBERD_AUTH_METHOD=internal anonymous
```
[External authentication](http://docs.ejabberd.im/admin/guide/configuration/#external-script) example:
```
EJABBERD_AUTH_METHOD=external
EJABBERD_EXTAUTH_PROGRAM="/opt/ejabberd/scripts/authenticate-user.sh"
EJABBERD_EXTAUTH_INSTANCES=3
EJABBERD_EXTAUTH_CACHE=600
```
**EJABBERD_EXTAUTH_INSTANCES** must be an integer with a minimum value of 1. **EJABBERD_EXTAUTH_CACHE** can be set to "false" or an integer value representing cache time in seconds. Note that caching should not be enabled if internal auth is also enabled.
### MySQL Authentication
Set `EJABBERD_AUTH_METHOD=external` and `EJABBERD_EXTAUTH_PROGRAM=/opt/ejabberd/scripts/lib/auth_mysql.py` to enable MySQL authentication. Use the following environment variables to configure the database connection and the layout of the database. Password changing, registration, and unregistration are optional features and are enabled only if the respective queries are provided.
- **AUTH_MYSQL_HOST**: The MySQL host
- **AUTH_MYSQL_USER**: Username to connect to the MySQL host
- **AUTH_MYSQL_PASSWORD**: Password to connect to the MySQL host
- **AUTH_MYSQL_DATABASE**: Database name where to find the user information
- **AUTH_MYSQL_HASHALG**: Format of the password in the database. Default is cleartext. Options are `crypt`, `md5`, `sha1`, `sha224`, `sha256`, `sha384`, `sha512`. `crypt` is recommended, as it is salted. When setting the password, `crypt` uses SHA-512 (prefix `$6$`).
- **AUTH_MYSQL_QUERY_GETPASS**: Get the password for a user. Use the placeholders `%(user)s`, `%(host)s`. Example: `SELECT password FROM users WHERE username = CONCAT(%(user)s, '@', %(host)s)`
- **AUTH_MYSQL_QUERY_SETPASS**: Update the password for a user. Leave empty to disable. Placeholder `%(password)s` contains the hashed password. Example: `UPDATE users SET password = %(password)s WHERE username = CONCAT(%(user)s, '@', %(host)s)`
- **AUTH_MYSQL_QUERY_REGISTER**: Register a new user. Leave empty to disable. Example: `INSERT INTO users ( username, password ) VALUES ( CONCAT(%(user)s, '@', %(host)s), %(password)s )`
- **AUTH_MYSQL_QUERY_UNREGISTER**: Removes a user. Leave empty to disable. Example: `DELETE FROM users WHERE username = CONCAT(%(user)s, '@', %(host)s)`
Note that the MySQL authentication script writes a debug log into the file `/var/log/ejabberd/extauth.log`. To get its content, execute the following command:
```bash
docker exec -ti ejabberd tail -n50 -f /var/log/ejabberd/extauth.log
```
To find out more about the mysql authentication script, check out the [ejabberd-auth-mysql](https://github.com/rankenstein/ejabberd-auth-mysql) repository.
### LDAP Auth
Full documentation http://docs.ejabberd.im/admin/guide/configuration/#ldap.
Connection
- **EJABBERD_LDAP_SERVERS**: List of IP addresses or DNS names of your LDAP servers. This option is required.
- **EJABBERD_LDAP_ENCRYPT**: The value `tls` enables encryption by using LDAP over SSL. The default value is: `none`.
- **EJABBERD_LDAP_TLS_VERIFY**: `false|soft|hard` This option specifies whether to verify LDAP server certificate or not when TLS is enabled. The default is `false` which means no checks are performed.
- **EJABBERD_LDAP_TLS_CACERTFILE**: Path to file containing PEM encoded CA certificates.
- **EJABBERD_LDAP_TLS_DEPTH**: Specifies the maximum verification depth when TLS verification is enabled. The default value is 1.
- **EJABBERD_LDAP_PORT**: The default port is `389` if encryption is disabled; and `636` if encryption is enabled.
- **EJABBERD_LDAP_ROOTDN**: Bind DN. The default value is "" which means anonymous connection.
- **EJABBERD_LDAP_PASSWORD**: Bind password. The default value is "".
- **EJABBERD_LDAP_DEREF_ALIASES**: `never|always|finding|searching`
Whether or not to dereference aliases. The default is `never`.
Authentication
- **EJABBERD_LDAP_BASE**: LDAP base directory which stores users accounts. This option is required.
- **EJABBERD_LDAP_UIDS**: `ldap_uidattr:ldap_uidattr_format` The default attributes are `uid:%u`.
- **EJABBERD_LDAP_FILTER**: RFC 4515 LDAP filter. The default Filter value is undefined.
- **EJABBERD_LDAP_DN_FILTER**: `{ Filter: FilterAttrs }` This filter is applied on the results returned by the main filter. By default ldap_dn_filter is undefined.
## Admins
Set one or more admin user (seperated by whitespace) with the **EJABBERD_ADMINS** environment variable. You can register admin users with the **EJABBERD_USERS** environment variable during container startup, use you favorite XMPP client or the `ejabberdctl` command line utility.
```
EJABBERD_ADMINS=admin@example.ninja
```
## Users
Automatically register users during container startup. Uses random password if you don't provide a password for the user. Format is `JID:PASSWORD`. Register more users separated with whitespace.
Register the admin user from **EJABBERD_ADMINS** with a give password:
```
EJABBERD_USERS=admin@example.ninja:password1234
```
Or without a random password printed to stdout (check container logs):
```
EJABBERD_USERS=admin@example.ninja
```
Register more than one user:
```
EJABBERD_USERS=admin@example.ninja:password1234 user1@test.com user1@xyz.io
```
## SSL
- **EJABBERD_SSLCERT_HOST**: SSL Certificate for the hostname.
- **EJABBERD_SSLCERT_EXAMPLE_COM**: SSL Certificates for XMPP domains.
- **EJABBERD_STARTTLS**: Set to `false` to disable StartTLS for client to server connections. Default: `true`.
- **EJABBERD_S2S_SSL**: Set to `false` to disable SSL in server 2 server connections. Default: `true`.
- **EJABBERD_HTTPS**: If your proxy terminates SSL you may want to disable HTTPS on port 5280 and 5443. Default: `true`.
- **EJABBERD_PROTOCOL_OPTIONS_TLSV1**: Allow TLSv1 protocol. Default: `false`.
- **EJABBERD_PROTOCOL_OPTIONS_TLSV1_1**: Allow TLSv1.1 protocol. Default: `true`.
- **EJABBERD_CIPHERS**: Cipher suite. Default: `HIGH:!aNULL:!3DES`.
- **EJABBERD_DHPARAM**: Set to `true` to use or generate custom DH parameters. Default: `false`.
## Modules
- **EJABBERD_SKIP_MODULES_UPDATE**: If you do not need to update ejabberd modules specs, skip the update task and speedup start. Default: `false`.
- **EJABBERD_MOD_MUC_ADMIN**: Activate the mod_muc_admin module. Default: `false`.
- **EJABBERD_MOD_ADMIN_EXTRA**: Activate the mod_muc_admin module. Default: `true`.
- **EJABBERD_REGISTER_TRUSTED_NETWORK_ONLY**: Only allow user registration from the trusted_network access rule. Default: `true`.
- **EJABBERD_MOD_VERSION**: Activate the mod_version module. Default: `true`.
## Logging
Use the **EJABBERD_LOGLEVEL** environment variable to set verbosity. Default: `4` (Info).
```
loglevel: Verbosity of log files generated by ejabberd.
0: No ejabberd log at all (not recommended)
1: Critical
2: Error
3: Warning
4: Info
5: Debug
```
## Mount Configurations
If you prefer to use your own configuration files and avoid passing docker environment variables (```-e```), you can do so by mounting a host directory.
Pass in an additional ```-v``` to the ```docker run``` command, like so:
```
docker run -d \
--name "ejabberd" \
-p 5222:5222 \
-p 5269:5269 \
-p 5280:5280 \
-h 'xmpp.example.de' \
-v /<host_path>/conf:/opt/ejabberd/conf \
rroemhild/ejabberd
```
Your ```/<host_path>/conf``` folder should look like so:
```
/<host_path>/conf/
├── ejabberdctl.cfg
├── ejabberd.yml
└── inetrc
```
Example configuration files can be downloaded from the ejabberd [github](https://github.com/rroemhild/ejabberd) page.
When these files exist in ```/opt/ejabberd/conf```, the run script will ignore the configuration templates.
## Erlang Configuration
With the following environment variables you can configure options that are passed by ejabberdctl to the erlang runtime system when starting ejabberd.
- **POLL**: Set to `false` to disable Kernel polling. Default: `true`.
- **SMP**: SMP support `enable`, `auto`, `disable`. Default: `auto`.
- **ERL_MAX_PORTS**: Maximum number of simultaneously open Erlang ports. Default: `32000`.
- **FIREWALL_WINDOW**: Range of allowed ports to pass through a firewall. Default: `not defined`.
- **INET_DIST_INTERFACE**: IP address where this Erlang node listens other nodes. Default: `0.0.0.0`.
- **ERL_EPMD_ADDRESS**: IP addresses where epmd listens for connections. Default: `0.0.0.0`.
- **ERL_PROCESSES**: Maximum number of Erlang processes. Default: `250000`.
- **ERL_MAX_ETS_TABLES**: Maximum number of Erlang processes. Default: `1400`.
- **ERLANG_OPTIONS**: Overwrite additional options passed to erlang while starting ejabberd. Default: `-noshell`
- **ERLANG_NODE**: Allows to explicitly specify erlang node for ejabberd. Set to `nodename` lets erlang add the hostname. Default: `ejabberd@localhost`.
- **EJABBERD_CONFIG_PATH**: ejabberd configuration file. Default: `/opt/ejabberd/conf/ejabberd.yml`.
- **CONTRIB_MODULES_PATH**: contributed ejabberd modules path. Default: `/opt/ejabberd/modules`.
- **CONTRIB_MODULES_CONF_DIR**: configuration directory for contributed modules. Default: `/opt/ejabberd/modules/conf`.
- **ERLANG_COOKIE**: Set erlang cookie. Default is to auto-generated cookie.
# Maintenance
The `ejabberdctl` command is in the search path and can be run by:
```bash
docker exec CONTAINER ejabberdctl help
```
## Register Users
```bash
docker exec CONTAINER ejabberdctl register user XMPP_DOMAIN PASSWORD
```
## Creating Backups
Create a backupfile with ejabberdctl and copy the file from the container to localhost
```bash
docker exec CONTAINER ejabberdctl backup /opt/ejabberd/backup/ejabberd.backup
docker cp CONTAINER:/opt/ejabberd/backup/ejabberd.backup /tmp/ejabberd.backup
```
## Restoring Backups
Copy the backupfile from localhost to the running container and restore with ejabberdctl
```bash
docker cp /tmp/ejabberd.backup CONTAINER:/opt/ejabberd/backup/ejabberd.backup
docker exec CONTAINER ejabberdctl restore /opt/ejabberd/backup/ejabberd.backup
```
# Debug
## Erlang Shell
Set `-i` and `-t` option and append `live` to get an interactive erlang shell:
```bash
docker run -i -t -P rroemhild/ejabberd live
```
You can terminate the erlang shell with `q().`.
## System Shell

#
# In this file you can configure options that are passed by ejabberdctl
# to the erlang runtime system when starting ejabberd
#
#' POLL: Kernel polling ([true|false])
#
# The kernel polling option requires support in the kernel.
# Additionally, you need to enable this feature while compiling Erlang.
#
# Default: true
#
POLL={{ env['POLL'] or 'true' }}
#.
#' SMP: SMP support ([enable|auto|disable])
#
# Explanation in Erlang/OTP documentation:
# enable: starts the Erlang runtime system with SMP support enabled.
# This may fail if no runtime system with SMP support is available.
# auto: starts the Erlang runtime system with SMP support enabled if it
# is available and more than one logical processor are detected.
# disable: starts a runtime system without SMP support.
#
# Default: auto
#
SMP={{ env['SMP'] or 'auto' }}
#.
#' ERL_MAX_PORTS: Maximum number of simultaneously open Erlang ports
#
# ejabberd consumes two or three ports for every connection, either
# from a client or from another Jabber server. So take this into
# account when setting this limit.
#
# Default: 32000
# Maximum: 268435456
#
ERL_MAX_PORTS={{ env['ERL_MAX_PORTS'] or '32000' }}
#.
#' FIREWALL_WINDOW: Range of allowed ports to pass through a firewall
#
# If Ejabberd is configured to run in cluster, and a firewall is blocking ports,
# it's possible to make Erlang use a defined range of port (instead of dynamic
# ports) for node communication.
#
# Default: not defined
# Example: 4200-4210
#
{%- if env['FIREWALL_WINDOW'] %}
FIREWALL_WINDOW={{ env['FIREWALL_WINDOW'] }}
{%- endif %}
#.
#' INET_DIST_INTERFACE: IP address where this Erlang node listens other nodes
#
# This communication is used by ejabberdctl command line tool,
# and in a cluster of several ejabberd nodes.
#
# Default: 0.0.0.0
#
{%- if env['INET_DIST_INTERFACE'] %}
INET_DIST_INTERFACE={{ env['INET_DIST_INTERFACE'] }}
{%- endif %}
#.
#' ERL_EPMD_ADDRESS: IP addresses where epmd listens for connections
#
# IMPORTANT: This option works only in Erlang/OTP R14B03 and newer.
#
# This environment variable may be set to a comma-separated
# list of IP addresses, in which case the epmd daemon
# will listen only on the specified address(es) and on the
# loopback address (which is implicitly added to the list if it
# has not been specified). The default behaviour is to listen on
# all available IP addresses.
#
# Default: 0.0.0.0
#
{%- if env['ERL_EPMD_ADDRESS'] %}
ERL_EPMD_ADDRESS={{ env['ERL_EPMD_ADDRESS'] }}
{%- endif %}
#.
#' ERL_PROCESSES: Maximum number of Erlang processes
#
# Erlang consumes a lot of lightweight processes. If there is a lot of activity
# on ejabberd so that the maximum number of processes is reached, people will
# experience greater latency times. As these processes are implemented in
# Erlang, and therefore not related to the operating system processes, you do
# not have to worry about allowing a huge number of them.
#
# Default: 250000
# Maximum: 268435456
#
ERL_PROCESSES={{ env['ERL_PROCESSES'] or '250000' }}
#.
#' ERL_MAX_ETS_TABLES: Maximum number of ETS and Mnesia tables
#
# The number of concurrent ETS and Mnesia tables is limited. When the limit is
# reached, errors will appear in the logs:
# ** Too many db tables **
# You can safely increase this limit when starting ejabberd. It impacts memory
# consumption but the difference will be quite small.
#
# Default: 1400
#
ERL_MAX_ETS_TABLES={{ env['ERL_MAX_ETS_TABLES'] or '1400' }}
#.
#' ERL_OPTIONS: Additional Erlang options
#
# The next variable allows to specify additional options passed to erlang while
# starting ejabberd. Some useful options are -noshell, -detached, -heart. When
# ejabberd is started from an init.d script options -noshell and -detached are
# added implicitly. See erl(1) for more info.
#
# It might be useful to add "-pa /usr/local/lib/ejabberd/ebin" if you
# want to add local modules in this path.
#
# Default: ""
#
ERL_OPTIONS="{{ env['ERL_OPTIONS'] or '-noshell' }}"
#.
#' ERLANG_NODE: Erlang node name
#
# The next variable allows to explicitly specify erlang node for ejabberd
# It can be given in different formats:
# ERLANG_NODE=ejabberd
# Lets erlang add hostname to the node (ejabberd uses short name in this case)
# ERLANG_NODE=ejabberd@hostname
# Erlang uses node name as is (so make sure that hostname is a real
# machine hostname or you'll not be able to control ejabberd)
# ERLANG_NODE=ejabberd@hostname.domainname
# The same as previous, but erlang will use long hostname
# (see erl (1) manual for details)
#
# Default: ejabberd@localhost
#
ERLANG_NODE={{ env['ERLANG_NODE'] or 'ejabberd@localhost' }}
#.
#' EJABBERD_PID_PATH: ejabberd PID file
#
# Indicate the full path to the ejabberd Process identifier (PID) file.
# If this variable is defined, ejabberd writes the PID file when starts,
# and deletes it when stops.
# Remember to create the directory and grant write permission to ejabberd.
#
# Default: don't write PID file
#
#EJABBERD_PID_PATH=/var/run/ejabberd/ejabberd.pid
#.
#' EJABBERD_CONFIG_PATH: ejabberd configuration file
#
# Specify the full path to the ejabberd configuration file. If the file name has
# yml or yaml extension, it is parsed as a YAML file; otherwise, Erlang syntax is
# expected.
#
# Default: $ETC_DIR/ejabberd.yml
#
EJABBERD_CONFIG_PATH={{ env['EJABBERD_CONFIG_PATH'] or '/opt/ejabberd/conf/ejabberd.yml' }}
#.
#' CONTRIB_MODULES_PATH: contributed ejabberd modules path
#
# Specify the full path to the contributed ejabberd modules. If the path is not
# defined, ejabberd will use ~/.ejabberd-modules in home of user running ejabberd.
#
# Default: $HOME/.ejabberd-modules
#
CONTRIB_MODULES_PATH={{ env['CONTRIB_MODULES_PATH'] or '/opt/ejabberd/modules' }}
#.
#' CONTRIB_MODULES_CONF_DIR: configuration directory for contributed modules
#
# Specify the full path to the configuration directory for contributed ejabberd
# modules. In order to configure a module named mod_foo, a mod_foo.yml file can
# be created in this directory. This file will then be used instead of the
# default configuration file provided with the module.
#
# Default: $CONTRIB_MODULES_PATH/conf
#
CONTRIB_MODULES_CONF_DIR={{ env['CONTRIB_MODULES_CONF_DIR'] or '/opt/ejabberd/modules/conf' }}
