1. Create Docker container Grafana
“ docker run -d –name= Grafana -p 3000:3000 -e “GF_SECURITY_ADMIN_USER= admin” -e “GF_SECURITY_ADMIN_PASSWORD=password” grafana/grafana:latest ”
2. Create Docker Container Loki
“ docker run -d –name= Loki -v /opt/Loki+Promtail/loki-config.yml:/mnt/config -p 3100:3100 grafana:loki”
After creating a loki docker container you need to create a folder and create .yml
“ mkdir /opt/Loki+Promtail ”
“ touch /opt/Loki+Promtail/loki-config.yml ”
Loki-config.yml
==============
auth_enabled: false

http_listen_port: 3100

3. Create docker container Promtail
This one is a default create docker container “promtail”
“ docker run -d –name Promtail -v /opt/:/mnt/config -v /var/log/:/var/log -p 9080:9080 –link Loki grafana:promtail –config.file=/mnt/config/promtail-config.yml ”
If you want to input another log file, you can create like that.
“ docker run -d –name Promtail -v /opt/:/mnt/config -v /opt/tomcat/logs/:/var/log /Tomcat-Server -v /root/tomcat-container/:/var/log/tomcat-container -p 9080:9080 –link Loki grafana/promtail –config.file=/mnt/config/promtail-config.yml ”
After creating a docker container you will need to create a folder config yml directory
“ mkdir /opt/Loki+Promtail/ ”
“ touch /opt/Loki+Promtail/promtail-config.yml ”
“ nano /opt/Loki+Promtail/promtial-config.yml ”
server:
http_listen_port: 9080
grpc_listen_port: 0
positions:
filename: /tmp/positions.yaml
clients:
– url: http://165.22.53.78:3100/loki/api/v1/push
scrape_configs:
– job_name: system
static_configs:
– targets:
– localhost
labels:
job: varlogs
__path__: /var/log/*log
– job_name: TOMCAT-SERVER
static_configs:
– targets:
– localhost
labels:

__path__: /var/log/TOMCAT-SERVER/*log
– job_name: tomcat-docker
static_configs:
– targets:
– localhost
labels:
job: tomcat-docker
__path__: /var/log/tomcat-docker/*log
After all create a docker container, Open Grafana Url before you create “ docker grafana ” Port and use it with your localhost or IP
To Add Data Source click “ Toggle Menu ” at left side of “ Home ” and click Data Source
After that click + add new data source on right side top corner and choice Loki
1. You can replace Name if you wish
2. Put URL when you create loki container port Example “ http://localhost:3101 ”
This 2 step finished score down,You will see save & test. When you click save & test you will see “ Data source connected and labels found. ”
When you see that your Data logs are connected.
To Check Data Logs click “ Explore ” and choose what you want to see logs.
