Observium docker image and docker-compose.yml

Built with RANCID, rsyslog, and smokeping

1. Install docker, docker-compose and git

2. Clone this repository

$ git clone $THIS_GIT_REPO
$ cd observium

3. Set config

   • Open and modify mysql.env, if you want to configure parameters.
   • Open and modify observium.env, and change the domain and admin credentials.
   • Set Timezone and Lang in system.env

4. Open docker-compose.yml

   • Set ports if desired. Observium listens on 8080, 514/udp for syslog.
   • Below are the list of volumes used:

• /data/docker/observium/data/mysql - MySQL
• /data/docker/observium/data/rrd - rrd
• /data/docker/observium/data/logs - observium logs
• /data/docker/observium/data/html - html data
• /data/docker/observium/data/mibs - mibs snmp
• /data/docker/observium/data/scripts - scripts
• /data/docker/observium/data/ssh_keys - Read later for ssh key details
• /data/docker/observium/data/rancid_configs - set RANCID config here
• /data/docker/observium/data/rancid_logs - RANCID logs

5. Start the services

$ docker-compose up -d

6. What is id_rsa for? Using RANCID to connect to network devices without a password, it should have a key to log in. Do not set a passphrase on the key. Devices should have a user named rancid.

$ ssh-keygen -t rsa
$ scp ~/.ssh/id_rsa.pub admin@<mikrotik_ip>:mykey.pub

This is the easiest method for building, but it leaves the credentials in docker history.

cd images
docker build \
  --build-arg INSTALL_METHOD=pro \
  --build-arg SVN_USER=MYUSER \
  --build-arg SVN_PASS=SECRET \
  -t observium \
  .

In order to build without saving the credentials, use this approach instead:

cd images
svn co -q $SVN_REPO --username $SVN_USER --password $SVN_PASS observium
docker build \
  --build-arg INSTALL_METHOD=pro \
  --build-arg SVN_USER=MYUSER \
  --build-arg SVN_PASS=SECRET \
  -t observium \
  .
