I did the following:
https://github.com/dockersamples/example-voting-app
cd example-voting-app
Inside that there are number of files/folders
MAINTAINERS
LICENSE
Jenkinsfile
ExampleVotingApp.sln
README.md
docker-stack-windows-1809.yml
docker-stack-simple.yml
docker-compose.yml
docker-compose-windows.yml
docker-compose-windows-1809.yml
docker-compose-simple.yml
docker-compose-k8s.yml
docker-compose-javaworker.yml
architecture.png
kube-deployment.yml
k8s-specifications
docker-stack.yml
docker-stack-windows.yml
result
vote
worker
I did cd vote
and executed following commands
docker build . -t voting-app
docker run -p 5000:80 voting-app
After I run docker run
command, I see the following output, and nothing is happening . I am clueless, as there is no error messages etc.
[root@osboxes vote]# docker run -p 5000:80 voting-app

Please guide how to fix this issue, and how to get the vote app running on container.
My OS details are as follows:
NAME="CentOS Linux"
VERSION="7 (Core)"
Thanks

In my earlier answer, i got the app working, by building and running each image individually.
Finally, after spending few hours, I am finally able to create docker-compose.yml
file and able to run the entire application using the following command:
docker-compose up
Hope it helps other who are struggling to make this application work.
docker-compose.yml
version: "3"
services:
redis:
image: redis
db:
image: postgres:9.4
environment:
- POSTGRES_PASSWORD=postgres
- POSTGRES_HOST_AUTH_METHOD=trust
vote:
image: voting-app
ports:
- 5000:80
links:
- redis
worker:
image: worker-app
links:
- db
- redis
result:
image: result-app
ports:
- 5001:80
links:
- db

After code checkout, I followed the following steps, and got the voting application to run.
change to vote directory
docker run -d --name=redis redis
docker build . -t voting-app
docker run -p 5000:80 --link redis:redis voting-app
docker run -d --name=db -e POSTGRES_PASSWORD=postgres postgres:9.4
change to worker directory
docker build . -t worker-app
docker run --link redis:redis --link db:db worker-app
change to result directory
docker build . -t result-app
docker run -p 5001:80 --link db:db result-app
Access the URLs
http://<IP>:5000/
http://<IP>:5001/
Replace the IP with IP of your machine. Now I can access both the URLs.
