Environment Variables

基本变量

When you start the zabbix-server-pgsql image, you can adjust the configuration of the Zabbix server by passing one or more environment variables on the docker run command line.

DB_SERVER_HOST
This variable is IP or DNS name of PostgreSQL server. By default, value is ‘postgres-server’

DB_SERVER_PORT
This variable is port of PostgreSQL server. By default, value is ‘5432’.

POSTGRES_USER, POSTGRES_PASSWORD, POSTGRES_USER_FILE, POSTGRES_PASSWORD_FILE
These variables are used by Zabbix server to connect to Zabbix database. With the _FILE variables you can instead provide the path to a file which contains the user / the password instead. Without Docker Swarm or Kubernetes you also have to map the files. Those are exclusive so you can just provide one type - either POSTGRES_USER or POSTGRES_USER_FILE!

docker run --name some-zabbix-server-pgsql -e DB_SERVER_HOST=“some-postgres-server” -v ./.POSTGRES_USER:/run/secrets/POSTGRES_USER -e POSTGRES_USER_FILE=/run/secrets/POSTGRES_USER -v ./.POSTGRES_PASSWORD:/run/secrets/POSTGRES_PASSWORD -e POSTGRES_PASSWORD_FILE=/var/run/secrets/POSTGRES_PASSWORD --init -d zabbix/zabbix-server-pgsql:tag
With Docker Swarm or Kubernetes this works with secrets. That way it is replicated in your cluster!

printf “zabbix” | docker secret create POSTGRES_USER -
printf “zabbix” | docker secret create POSTGRES_PASSWORD -
docker run --name some-zabbix-server-pgsql -e DB_SERVER_HOST=“some-postgres-server” -e POSTGRES_USER_FILE=/run/secrets/POSTGRES_USER -e POSTGRES_PASSWORD_FILE=/run/secrets/POSTGRES_PASSWORD --init -d zabbix/zabbix-server-pgsql:tag
By default, values for POSTGRES_USER and POSTGRES_PASSWORD are zabbix, zabbix.

POSTGRES_DB
The variable is Zabbix database name. By default, value is zabbix.

POSTGRES_USE_IMPLICIT_SEARCH_PATH
In some setups, for example including PgBouncer, setting the search_path via connection parameters fails. If this variable is set to “true”, the image skips setting the search_path and trusts that the search_path of the Zabbix user is setup correctly in PostgreSQL database.

ZBX_LOADMODULE
The variable is list of comma separated loadable Zabbix modules. It works with volume /var/lib/zabbix/modules. The syntax of the variable is dummy1.so,dummy2.so.

ZBX_DEBUGLEVEL
The variable is used to specify debug level. By default, value is 3. It is DebugLevel parameter in zabbix_server.conf. Allowed values are listed below:
0 - basic information about starting and stopping of Zabbix processes;
1 - critical information
2 - error information
3 - warnings
4 - for debugging (produces lots of information)
5 - extended debugging (produces even more information)

ZBX_TIMEOUT
The variable is used to specify timeout for processing checks. By default, value is 4.

ZBX_JAVAGATEWAY_ENABLE
The variable enable communication with Zabbix Java Gateway to collect Java related checks. By default, value is false.
