Docker image for running version 1.16 of osTicket.
This image has been created from the original docker-osticket image by Petter A. Helset.
It has a few modifications:
- Documentation added, hurray!
- Base OS image fixed to Alpine Linux
- AJAX issues fixed that made original image unusable
- Now designed to work with a linked MySQL docker container.
- Automates configuration file & database installation
- EMail support
osTicket is being served by nginx using PHP-FPM with PHP 8.0. PHP mail function is configured to use msmtp to send out-going messages.
Ensure you have a MySQL 5 container running that osTicket can use to store its data.
docker run -d \
-e MYSQL_ROOT_PASSWORD=secret \
-e MYSQL_USER=osticket \
-e MYSQL_PASSWORD=secret \
-e MYSQL_DATABASE=osticket \
--name osticket_mysql\
mysql:5
Now run this image and link the MySQL container.
docker run -d --name osticket --link osticket_mysql:mysql -p 8080:80 devinsolutions/osticket
Wait for the installation to complete then browse to your osTicket staff control panel at
http://localhost:8080/scp/
. Login with default admin user & password:
- username: ostadmin
- password: Admin1
Now configure as required. If you are intending on using this image in production, please make sure you change the passwords above and read the rest of this documentation!
Note (1): If you want to change the environmental database variables on the osTicket image to run, you can do it as follows.
docker run -d \
-e MYSQL_ROOT_PASSWORD=new_root_password \
-e MYSQL_USER=new_root_user \
-e MYSQL_PASSWORD=new_secret \
-e MYSQL_DATABASE=osticket \
--link osticket_mysql:mysql \
--name osticket\
-p 8080:80 \
devinsolutions/osticket
Note (2): osTicket automatically redirects http://localhost:8080/scp
to http://localhost/scp/
.
Either serve this on port 80 or don't omit the trailing slash after scp/
!
The recommended connection method is to link your MySQL container to this image with the alias name
mysql
. However, if you are using an external MySQL server then you can specify the connection
details using environmental variables.
osTicket requires that the MySQL connection specifies a user with full permissions to the specified database. This is required for the automatic database installation.
The osTicket configuration file is re-created from the template every time the container is started. This ensures the MySQL connection details are always kept up to date automatically in case of any changes.
There are no mandatory settings required when you link your MySQL container with the alias mysql
as per the quick start example.
The following environmental variables should be set when connecting to an external MySQL server.
MYSQL_HOST
The host name or IP address of the MySQL host to connect to. This is not required when you link a
container with the alias mysql
. This must be provided if not using a linked container.
MYSQL_PASSWORD
The password for the specified user used when connecting to the MySQL server. By default will use
the environmental variable MYSQL_PASSWORD
from the linked MySQL container if this is not
explicitly specified. This must be provided if not using a linked container.
MYSQL_PREFIX
The table prefix for this installation. Unlikely you will need to change this as customisable table prefixes are designed for shared hosting with only a single MySQL database available. Defaults to 'ost_'.
MYSQL_DATABASE
The name of the database to connect to. Defaults to 'osticket'.
MYSQL_USER
The user name to use when connecting to the MySQL server. Defaults to 'osticket'.
The image does not run a MTA. Although one could be installed quite easily, getting the setup so that external mail servers will accept mail from your host & domain is not trivial due to anti-spam measures. This is additionally difficult to do from ephemeral docker containers that run in a cloud where the host may change etc.
Hence this image supports osTicket sending of mail by sending directly to designated a SMTP server. However, you must provide the relevant SMTP settings through environmental variables before this will function.
To automatically collect email from an external IMAP or POP3 account, configure the settings for the relevant email address in your admin control panel as normal (Admin Panel -> Emails).
SMTP_HOST
The host name (or IP address) of the SMTP server to send all outgoing mail through. Defaults to 'localhost'.
SMTP_PORT
The TCP port to connect to on the server. Defaults to '25'. Usually one of 25, 465 or 587.
SMTP_FROM
The envelope from address to use when sending email (note that is not the same as the From:
header). This must be provided for sending mail to function. However, if not specified, this will
default to the value of SMTP_USER
if this is provided.
SMTP_TLS
Boolean (1 or 0) value indicating if TLS should be used to create a secure connection to the server. Defaults to true.
SMTP_TLS_CERTS
If TLS is in use, indicates file containing root certificates used to verify server certificate. Defaults to system installed ca certificates list. This would normally only need changed if you are using your own certificate authority or are connecting to a server with a self signed certificate.
SMTP_USER
The user identity to use for SMTP authentication. Specifying a value here will enable SMTP
authentication. This will also be used for the SMTP_FROM
value if this is not explicitly
specified. Defaults to no value.
SMTP_PASSWORD
The password associated with the user for SMTP authentication. Defaults to no value.
CRON_INTERVAL
Specifies how often (in minutes) that osTicket cron script should be ran to check for incoming emails. Defaults to 5 minutes. Set to 0 to disable running of cron script. Note that this works in conjuction with the email check interval specified in the admin control panel, you need to specify both to the value you'd like!
INSTALL_SECRET
Secret string value for osTicket installation. A random value is generated on start-up and
persisted in /var/lib/osticket/secret.txt
if this is not provided.
If using in production you should specify this so that re-creating the container does not cause your installation secret to be lost!
INSTALL_CONFIG
If you require a configuration file for osTicket with custom content then you should create one and mount it in your container as a volume. The placeholders for the MySQL connection must be retained as these will be populated automatically when the container starts. Set this environmental variable to the fully qualified file name of your custom configuration. If not specified, the default osTicket sample configuration file is used.
INSTALL_EMAIL
Helpdesk email account. This is placed in the configuration file as well as the DB during installation. Defaults to 'helpdesk@example.com'
INSTALL_URL
The full URL of the osTicket installation that will be set in the DB during installation.
This should be set to match the public facing URL of your osTicket site.
For example: https://help.example.com/osticket
. Defaults to http://localhost:8080/
.
This has no effect if the database has already been installed. In this case, you should change the Helpdesk URL in System Settings and Preferences in the admin control panel.
The remaining environmental variables can be used as a convenience to provide defaults during the automated database installation but most of these settings can be changed through the admin panel if required. These are only used when creating the initial database.
INSTALL_NAME
The name of the helpdesk to create if installing. Defaults to "My Helpdesk".
ADMIN_FIRSTNAME
First name of automatically created administrative user. Defaults to 'Admin'.
ADMIN_LASTNAME
Last name of automatically created administrative user. Defaults to 'User'.
ADMIN_EMAIL
Email address of automatically created administrative user. Defaults to 'admin@example.com'.
ADMIN_USERNAME
User name to use for automatically created administrative user. Defaults to 'ostadmin'.
ADMIN_PASSWORD
Password to use for automatically created administrative user. Defaults to 'Admin1'.
This image was put together relatively quickly and could probably be improved to meet other use cases.
