QUESTION
After having followed a tutorial about microserves and OAuth2 in Maven Spring Boot, I got a problem. I want to exclude a request from the authentication, so unauthorized data can be gotten. This only doesn't seem to work in the way I do it. Can someone help me with this?
Tutorial I followed: https://developer.okta.com/blog/2018/02/13/secure-spring-microservices-with-oauth#microservices-architectures-with-spring-boot--spring-cloud
What I tried:
@Configuration
@EnableResourceServer
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {
@Override
public void configure(HttpSecurity http) throws Exception {
http.requestMatcher(new RequestHeaderRequestMatcher("Authorization"))
.authorizeRequests()
.antMatchers("/**").authenticated()
.and()
.authorizeRequests()
.andMatchers(HttpMethod.GET, "/beers").permitAll();
}
}
I have to authenticate when I try to do the request. How do I solve this?
spring-security-oauth2-autoconfigure: 2.1.1.RELEASE
ANSWER
Answered 2020-Jun-13 at 06:44Firstly, your configuration is the same as the followings . Just removing those unnecessary duplicated authorizeRequests() and and() , which make it look more clearly :
http.requestMatcher(new RequestHeaderRequestMatcher("Authorization"))
.authorizeRequests()
.antMatchers("/**").authenticated()
.andMatchers(HttpMethod.GET, "/beers").permitAll();
It means spring security will only handle the requests if it has Authorization header. Otherwise ,the request will be ignored and no spring security stuff will apply to it.
So if the request has the Authorization header , it will then start to check the rules (i.e. those matcher things configured by authorizeRequests()) from the top to the bottom according to the declaration order.Once a rule is matched , the bottom rule will be ignored and will not be checked.
Since your first rule is to match every HTTP request ("/**") which makes all rules below it never execute and does not have any meaning.
On the other hand , if you want spring security totally ignore "/beers" even its request has Authorization header , you should configure WebSecurity to ignore it :
public void configure(WebSecurity web) throws Exception {
web.ignoring()
.antMatchers(HttpMethod.GET, "/beers");
}
QUESTION
I am doing a POC on simple microservices architecture using typical Spring cloud stack but instead of Eureka server, service discovery is to be made using spring-cloud-kubernetes which is not working.
The whole POC is here - https://github.com/dhananjay12/spring-microservices-using-spring-kubernetes
Gateway as a edge server and 2 downstream services- user-service and contact-us-service.
The k8 setup is in k8s folder.
The downstream services have following dependencies:
org.springframework.cloud
spring-cloud-starter-kubernetes
org.springframework.cloud
spring-cloud-starter-netflix-eureka-client
application.yml
server:
port: 8100
management:
endpoints:
web:
exposure:
include: '*'
spring:
cloud:
kubernetes:
enabled: true
reload:
enabled: true
eureka:
client:
enabled: false
bootstrap.yml:
spring:
application:
name: user-service
and annotation of @EnableDiscoveryClient in the main class.
The gateway service has too relevant kubernetes dependencies:
org.springframework.cloud
spring-cloud-starter-kubernetes
org.springframework.cloud
spring-cloud-starter-netflix-ribbon
org.springframework.cloud
spring-cloud-starter-kubernetes-ribbon
application.yml

eureka:
client:
enabled: false
logging:

org.springframework.gateway: TRACE
org.springframework.cloud.gateway: TRACE
org.springframework.cloud.loadbalancer: TRACE
management:
endpoints:
web:
exposure:
include: '*'
bootstrap.yml
spring:
application:
name: gateway
and annotation of @EnableDiscoveryClient in the main class.
Please see the deployment and service yaml here - https://github.com/dhananjay12/spring-microservices-using-spring-kubernetes/tree/master/k8s
I am able to get to gateway but it is not routing to downstream service like user-service:
For example - /user-service/users/getPublicMailingAddress
gives Whitable error page
and the logs in gateway shows:
2019-07-07 06:40:30.017 TRACE 1 --- [or-http-epoll-2] o.s.c.g.h.p.RoutePredicateFactory : Pattern "[/my-nginx-nginx-ingress-controller/**]" does not match against value "/user-service/users/getPublicMailingAddress"
ANSWER
Answered 2019-Jul-17 at 10:08Spring Cloud Kubernetes requires access to the Kubernetes API in order to be able to retrieve a list of addresses for pods running for a single service. If you use Kubernetes, you should just execute the following command:
kubectl create clusterrolebinding admin --clusterrole=cluster-admin --serviceaccount=default:default

/bin/sh does not find ./run.sh although it is there in the file system, as proven by ls run.sh. Also, cat shows the content of run.sh:

#!/bin/sh
echo "********************************************************"
echo "Starting simple-service "
echo "********************************************************"
java -jar /usr/local/simple-service/simple-service-0.0.1-SNAPSHOT.jar
When I run vi from sh and copy the content of run.sh into a new file myrun.sh and make myrun.sh executable, I can execute ./myrun.sh and the spring service starts.
What is going on here? Why would sh not see an executable which is there in the filesystem? Executables from PATH or executables which I add manually run fine.
I am running Docker on Windows 10.
ANSWER
Answered 2017-Apr-22 at 08:34OK the reason is, run.sh is created with Windows line endings in the docker image if you check out with automatic lf->crlf conversion. One possible solution is to tell git not to convert line endings.
QUESTION
I am reading this release announcement for Spring Cloud dataflow. https://spring.io/blog/2017/02/22/spring-cloud-data-flow-for-cloud-foundry-1-1-1-maintenance-release-available
I am wondering if we need a minimum version of cloud foundry for successfully running spring cloud data applications.. Given that this stream of work is actually targeted for cloud based environments, i think they should also mention the minimum base Cloud Foundry versions that can support them.
Does this require an inter-process communication that's being made available in latest cloud foundry versions https://www.cloudfoundry.org/meet-new-container-networking-stack-cloud-foundry/ https://content.pivotal.io/blog/building-spring-microservices-with-cloud-foundrys-new-container-networking-stack
I do see the mention of PCF version compatibility for Spring Cloud Tasks http://docs.spring.io/spring-cloud-dataflow-server-cloudfoundry/docs/current-SNAPSHOT/reference/htmlsingle/#_version_compatibility
But i haven't been able to find the Base cloud foundry version that supports the features of Spring Cloud Data Flow in general or per feature compatibility breakdown with Cloud foundry versions. We are running IBM Bluemix in our company and are upgrading to the cf version that supports Deigo architecture (vs the current DEA) - don't know the exact version of CF will that be.
If we know the Spring Cloud Data flow feature compatibility with specific Cloud Foundry versions we can decide our adoption strategy accordingly.
ANSWER
Answered 2017-Mar-01 at 18:34Please refer to PCF vs. OSS CF compatibility matrix from the project site.
This matrix captures the baseline OSS CF release required to run SCDF on the particular PCF versions. You could further dive into respective PCF release-notes to double check other OSS components (eg., CAPI) for more granular compatibility measurements.
Tasks in SCDF, in particular, is GA'd with PCF 1.9; so if you're planning to use it, you'd have to be at least on OSS CF 246 release.
