75+
Another option to configure Eiffel-Intelligence Front-end is to provide the application properties file into the container, which can be made in two ways:
76+
1. Put application.properties file in Tomcat Catalina config folder in container and run Eiffe-Intelligence Front-end:
77+
78+
`docker run -p 8070:8080 --expose 8080 --volume /path/to/application.properties:/usr/local/tomcat/config/application.properties eiffel-intelligence-frontend:0.0.19`
79+
80+
2. Put application.properties file in a different folder in container and tell EI where the application.properties is located in the container:
81+
82+
`docker run -p 8070:8080 --expose 8080 --volume /path/to/application.properties:/tmp/application.properties -e spring.config.location=/tmp/application.properties eiffel-intelligence-frontend:0.0.19`
83+
84+
85+
# Run Docker image with provided docker-compose file
86+
This docker-compose file includes these components, [docker-compose.yml](https://github.com/Ericsson/eiffel-intelligence-frontend/blob/master/src/main/docker/docker-compose.yml):
87+
- MongoDb
88+
- RabbitMq
89+
- ER
90+
- EI-Backend
91+
- EI-Frontend (Using the local EI-Frontend Docker image build from previous steps)
92+
93+
If you have used a different image tag when you build the EI Frontend docker image, then you need to update docker-compose.yml file.
94+
95+
This line need to changed, in ei_backend service section:
96+
97+
"image: eiffel-intelligence-frontend:0.0.19"
98+
99+
To:
100+
101+
"image: \<your image tag\>"
102+
103+
Two variables need to be set before we can start up all services with docker-compose tool.
104+
Set Docker host ip to the HOST variable.
105+
If on Linux:
106+
107+
`export HOST=$(hostname -I | tr " " "\n"| head -1)`
108+
109+
If on Windows, get Docker Host ip with command: `dockermachine ip`
110+
111+
Set that Docker host ip to HOST environment varaible.
112+
113+
Currently we need to provide EI Back-end instances list outside of docker-compose.yml file.
114+
115+
`export EIFFEL2_EI_FRONTEND_EI_INSTANCES_LIST=$(echo [{ \"contextPath\": \"\", \"port\": \"8080\", \"name\": \"EI-Backend\", \"host\": \"ei-backend\", \"https\": false, \"defaultBackend\": true}])`
116+
117+
Then run following docker-compose command to startup all components:
118+
119+
`docker-compose -f src/main/docker/docker-compose.yml up -d`
120+
121+
It will take some minutes until all components has started. When all components has loaded, you should be able to access EI Front-end web page with address:
122+
http://\<docker host ip\>:8081/
123+
124+
Curl command can be used to make request via EI Front-end bridge to EI Back-end Rest-Api, example for getting all subscriptions:
125+
126+
127+
`curl -X GET http://localhost:8081/subscriptions`
128+
129+
It is also possible to access these Rest-Api addresses in web-browser and get result presented in a Json view in web-browser.
130+
131+
Following command can be used to get the logs from the EI Front-end container/service:
132+
133+
`docker-compose -f src/main/docker/docker-compose.yml logs ei_frontend`
134+
135+
All service names can be retreived with following command:
136+
137+
`docker-compose -f src/main/docker/docker-compose.yml config --services`
138+
139+
It is also possible to retrieve the logs by only using "docker logs <container_id or container_name>" command:
140+
141+
`docker logs <container_id or container_name>`
142+
143+
Container id can be retrieved with docker command:
73144

145+
`docker ps`
