You need to update documentation to reflect your image name and version on some of your docker run examples.

docker run -d --name config-server -p 8888:8888 anilallewar/config-server

Should be

docker run -d --name config-server -p 8888:8888 anilallewar/basic-config-server:0.0.1

Dockercompoise appears OK

I know this project is an example but in real world should I have one config-server and one service-registry for each application?
Or should I have a global config server and a global service-registry which all the services of all projects will use?

I couldn't access Eureka, User, Task and Comments services from browser after starting the application. Can you please mention the end point URLs to access the application and each service?

Using my browser for authentication works fine. I get redirected to auth-server, log in successfully and get redirected to zuul again and getting information from a protected microservice.

Using curl to obtain a token also works fine but using this token with the "Authorization: Bearer xxx..." header to get a resource doesn't work. I always get redirected to the login page.

Maybe this is related to:
kakawait/uaa-behind-zuul-sample#13

The documentation from the auth-server (in this project) says that getting resources via curl should be also possible. What am i doing wrong?

UPDATE
Got it working using @ResourceServer annotation instead of @EnableOAuth2Sso annotation (both isn't possible so easy at this time) and extending ResourceServerConfigurerAdapter.

...
@EnableResourceServer
public class ZuulServerApplication extends ResourceServerConfigurerAdapter {
...

I would be glad if you could provide a solution which is able to handle both.

Its great microservice project, I am using this template as my reference and developed a microservice application every thing working fine, now the problem is when i do the proxy call to the microservices the data from microservice are coming as excepted but if I hit the url continuously getting the empty response..
What may be the reason for it?

When i run project with Rancher, ports exposed by Rancher are not reachable.
If you look at the picture you can see ports exposed but when i try to access it this failed.
Thanks
