QUESTION

Why does a Keycloak bearer token appear to be truncated during security filter chain processing

Asked 2022-Mar-24 at 08:15

I am working with Keycloak 16.1.0, spring boot 2.6.2 and an external application client that sends a bearer token in to my server application to the endpoint http://romanmed-host:8888/actuator/health.

By cranking the debugging level up to maximum, I can see the access token before its processed. I can verify that its accurate by using the JWT Debug site JSON Web Tokens to verify that the signature is correct.

Yet several lines later in the output log the same bearer token appears to be somewhat truncated, its listed with an error saying that it failed to verify. When checked by using the JWT site indicates a signature error, but the token content is correct.

Naturally I would like to know why it appears to be truncated and what I can do about it.

I can match the output from the client program to the server and its not been changed, so truncation must occur within the server program.
The program is accepting the request by a get request, since the token can be checked by JWT as valid at this point, its not truncated by the get request input method.
I have not inserted a filter in the security filter chain, so I can see how any of my code could be doing anything to invalid the token.
Other than the Failed to verify token no other error messages are generated, suggesting that until this point everything is correct.

I can see that the WebAsyncManagerIntegrationFilter, SecurityContextPersistenceFilter, HeaderWriterFilter,KeycloakPreAuthActionsFilter and KeycloakAuthenticationProcessingFilter have all been invoked.

I am assuming that the problem is somewhere within the KeycloakAuthenticationProcessingFilter, but I don't understand why the token appears to have been truncated at this point.

The received bearer token is

ANSWER

Answered 2022-Mar-07 at 08:32

The problem is the set up of the client and server programs.

The server used the value

auth-server-url: http://localhost:8085/auth

in its application.yml file to define the location of the Keycloak server, the client used the value

auth-server-url: http://romanmed-host:8085/auth

to define the location of Keycloak where the machine name romanmed-host is an alias for localhost. Having changed these values to be the same value, everything works as expected.

The diagnostics generated by the debugging/trace code are confusing, string described as truncated header seems to be truncated the bearer token, with out the signature. What the 'Keycloak` diagnostic is attempting to print is the part of the token which defines the tokens permissions and not the signature section.

Running the entire bearer token through the JWT site does show that the token is valid, because its a correctly encoded token and is legitimate.

The problem is not the token, but the way the token is being used! The client was expecting a legal signed token generated by them instance of Keycloak that it knew about, what it got was a legal signed token generated by Keycloak with a different address, which it correctly objected to.

The problem being the nature of the generated error message, it just claimed that the token signature was invalid, had it said something about an invalid/unexpected hostname, the nature of the problem would have been rather more obvious and resolved much faster. Keycloak is design to be flexible, so error messages tend to more vague to cover all situations, hence the message there is something wrong with your bearer token signature which is correct, but vague.

There seems to several schools of thought on how to resolve issues like this, one is to use an raw ip address which will always resolve to the same value. Thus avoid problems like this. This suffers from if the Keycloak server is moved to another machine there are lots of values to change.

My solution is to define an alias value in the hosts/dns server for the address of the eycloak server and always use that value in the support files. Hence if the Keycloak server is ever moved to another address, there is only one value to change.

QUESTION

Making request to Spring Boot Admin server from custom view?

Asked 2022-Jan-26 at 18:15

I'm trying to add a custom view with some administrative utilities to Spring Boot Admin. The idea is to implement these as endpoints in Springboot Admin and call these endpoints from my custom view, but I don't know how to make a call to the server itself.

When a custom view has parent: 'instances' it will get an axios client for connecting to the current instance, but since the view I'm building isn't tied to a specific instance it doesn't have this. I'm aware I can install axios as a dependency, but I'd like to avoid that if possible to reduce build times. Since SBA itself depends on axios it seems I shouldn't have to install it myself.

Based on this sample, this is what I have right now:

QUESTION

When running spring-boot container on kubernetes active processor count is set with host CPU, not k8s cpu limit for container

Asked 2022-Jan-10 at 16:34

We run spring-boot containers created using bootBuildImage gradle task on kubernetes. We provide both CPU limits and memory limits to the pods at startup in k8s. We use:

spring-boot version 2.6.2
docker image built with gradle spring-boot plugin bootBuildImage task
spring-boot-admin to administrate our spring-boot based deployments
JDK 11 (to enable blockhound)
32 CPUs hosts in GCP GKE
In dev we limit our container to 1 CPU and 1Gig of memory

We noticed that all our spring-boot based containers are provisioned (ie nb of threads) as if running on 32 CPUs instances.

Docker startup logs show

Setting Active Processor Count to 32

[...]

Picked up JAVA_TOOL_OPTIONS: [...] -XX:ActiveProcessorCount=32

In spring-boot-admin with see web servers (netty for reactive, undertow for servlet) are provisioned with thread pools as if the application was running on 32 CPUs allocated container even if the container was limited with 1 CPU by k8s. OTH the allocated memory to the JVM is correct.

How can we make sure the active CPU count reflects the k8s CPU limitation ?

Thanks in advance

ANSWER

Answered 2022-Jan-08 at 13:55

Based on the output you included, it looks like you're using buildpacks (i.e. ./mvnw spring-boot:build-image or ./gradlew bootBuildImage or pack build).

In that case, you can set the env variable JAVA_TOOL_OPTIONS with -XX:ActiveProcessorCount=x to override the default calculation. The default calculation will pull the total number of processors (as reported by Go's runtime.NumCPU() function).

Side note. What you are asking seems reasonable, so I opened an issue to see if we can enable it to detect the limited CPU count.

SpringBoot Admin custom authentication flow when accessing client

Asked 2021-May-06 at 16:09

I have a number of applications reporting to a SpringBoot Admin application using SpringBoot Admin Client. One of our recent projects that's under construction is using a custom JWT/refresh token authentication flow and I want SpringBoot Admin to use that before hitting the actuator endpoints so I can secure those as well.

The flow works by sending credentials to /v1/auth/login, which will give the user a JWT token with expiration date and refresh token. The JWT is only valid for a short time after which it needs to be refreshed and is submitted with the request as a Bearer-token.

I found this this thread which is somewhat related, but I need to be able to see which endpoint it's trying to access since not all of the applications use the same kind of authentication.

Is there some way I can configure it to add the Authorization header with the correct headers given a URL or client name that matches a certain pattern? Preferably as part of some component that could keep JWT/expiry/refresh token as part of it's state, so I could refresh it when necessary.

It seems that the path to the Maven repository isn't correctly initialized. As this issue describes the paths are written with \\ instead of / which GNU tar expects. The fix was already provided in Dec 2020, so it made it to the version v2.1.4. The last version v2.1.3 was released in November. But sadly there is a bug in pointing the v2 to the latest v2.1.4 (as normally expected by GitHub Actions users). Therefore to solve this issue, we need to explicitely specifiy the full actions/cache version v2.1.4 like this:
