Example 2 on this page https://[www.zabbix.com/documentation/current/manual/installation/containers|http://www.zabbix.com/documentation/current/manual/installation/containers] does not provide correct deployment.
Both zabbix-server-pgsql and zabbix-web-nginx-pgsql endlessly report
**** PostgreSQL server is not available. Waiting 5 seconds...
This is due to /usr/bin/docker-entrypoint.sh has following code to check connectivity to DB:
psql "$ssl_opts" --host ${DB_SERVER_HOST} --port ${DB_SERVER_PORT} --username ${DB_SERVER_ROOT_USER} --list --quiet
If dbname is not specified at the command line then psql uses user_name as dbname but DB zabbix does not exist, we created zabbix_dmp database instead. So this needs to be changed:
--- POSTGRES_DB="zabbix_pwd" +++ POSTGRES_DB="zabbix"
The second problem is with zabbix-web-nginx-pgsql container exposing wrong port, if we deploy this container as it is right now in documentation then ngnx is listening on port 8080, so this needs to be changed:
--- -p 443:8443 +++ -p <some_host_port>:8080
Bottom line, these are steps to deploy working configuration (without snmp_trapper):
docker run --name postgres-server -t -e POSTGRES_USER="zabbix" -e POSTGRES_PASSWORD="zabbix" -e POSTGRES_DB="zabbix" --restart unless-stopped -d postgres:latest docker run --name zabbix-server-pgsql -t -e DB_SERVER_HOST="postgres" -e POSTGRES_USER="zabbix" -e POSTGRES_PASSWORD="zabbix" -e POSTGRES_DB="zabbix" --link postgres-server:postgres -p 11051:10051 --restart unless-stopped -d zabbix/zabbix-server-pgsql:latest docker run --name zabbix-web-nginx-pgsql -t -e DB_SERVER_HOST="postgres" -e POSTGRES_USER="zabbix" -e POSTGRES_PASSWORD="zabbix" -e POSTGRES_DB="zabbix" --link postgres-server:postgres --link zabbix-server-pgsql:zabbix-server -p 8080:8080 -v /etc/ssl/nginx:/etc/ssl/nginx:ro --restart unless-stopped -d zabbix/zabbix-web-nginx-pgsql:latest
