docker-xymon

Dockerization of the Xymon monitoring system on an Ubuntu base

Quick Start

docker run -d -p 80:80 -p 1984:1984 -v /etc/xymon:/etc/xymon -v /var/lib/xymon:/var/lib/xymon --name xymon deweysasser/xymon

or use docker-compose with

xymon:
  image: deweysasser/xymon
  ports:
    - 80:80
    - 1984:1984
  volumes:
    - xymon-config:/etc/xymon
    - xymon-data:/var/lib/xymon
  environment:
    SSMTP_mailhub: mail.example.com
    SSMTP_AuthUser: user
    SSMTP_AuthPass: password
    SSMTP_AuthMethod: LOGIN
    SSMTP_UseTLS: "Yes"

Interface

Ports

• 80 -- Web server
• 1984 -- Xymon/bb client reporting port

You only need to expose port 1984 if you are going to use a xymon client (e.g. native, Windows or docker).

Port 1984 should NOT be exposed to public (Internet facing) traffic.

Sending Mail

Any environment variables with the prefix SSMTP_ have the prefix stripped and are otherwise copied verbatim into /etc/ssmtp/ssmtp.conf.

You will need at least the environment variable SSMTP_mailhub and will likely want:

• SSMTP_mailhub
• SSMTP_AuthUser
• SSMTP_AuthPass
• SSMTP_AuthMethod=LOGIN
• SSMTP_UseTLS=Yes
• SSMTP_STARTTLS=Yes

You can also choose to configure the file in other ways, for example in a volume or by extending this docker image.

You may then configure Xymon alerts as usual.

See the documentation for SSMTP and Xymon alerts for more details.

Volumes

• /etc/xymon -- all xymon configuration data
• /var/lib/xymon -- xymon data (monitoring state)

Timezone

By default the container will use the posixrules TZ rule set. If you'd like to override this, set the environment variable 'TZ', e.g. docker run -d -e TZ=America/New_York

Known Issues

• Password protection on cgi directories is currently disabled
