            Jenkins - getting "No type prefix:" when assigning roles
            Asked 2022-Feb-25 at 10:29

            I am trying to assign roles to users in Jenkins using the 'role based strategy' plugin. When I do that, I am getting a red text that says "No type prefix:" in front of every user that I am assigning a role to. Please advise how this can be removed.:

            I am very new to Jenkins so any suggestions will be very helpful.

            Regards Ramesh



            Answered 2022-Feb-16 at 22:58

            use "USER:" for user and "GROUP:" for group .. eg "USER:ABC" ..this changed with the recent plug in update ..



            Jenkins Ambiguous Permission
            Asked 2022-Feb-01 at 14:15

            After updating Jenkins, it is sending a warning for ambiguous permission for project base permission. I can migrate the entry to user or group manually, was wondering if there's an automate or batch way to do so?

            Warning Messages

            Some permission assignments are ambiguous. It is recommended to update affected configurations to be unambiguous. See this overview page for a list of affected configurations.

            This table contains rows with ambiguous entries. This means that they apply to both users and groups of the specified name. If the current security realm does not distinguish between user names and group names unambiguously, and if users can either choose their own user name or create new groups, this configuration may allow them to obtain greater permissions. It is recommended that all ambiguous entries are replaced with ones that are either explicitly a user or group.

            I have deleted old entries and added them again, warning disappeared.



            C# WASM without Blazor
            Asked 2022-Jan-30 at 14:27

            I want to be able to call C# code from JavaScript. The mono project used to have a WASM SDK that you could download from their old Jenkins server, but that is no longer public. Existing docs tend to point toward those builds. The Azure Devops builds do not include this SDK. A few messages I've seen on their Github account indicate that they are now focusing on the .NET 6 for WASM. I do not wish to use the Blazor components. Is there a way in .NET 6 to build a minimally sized WASM binary without the Blazor UI?



            Answered 2021-Aug-26 at 01:25

            Yes it's absolutely possible. Blazor does not have a monopoly on C#/WASM and it's far from clear that it's going to wind up being the best long term option (and a lot of evidence it's not).

            I recommend starting with the Uno WASM Bootstrap.

            new info: The issue is now solved with upgrading the Kubernetes plugin to version: 1.31.2

            Pylint integration with Jenkins build running on dynamic kubernetes pods as agents
            Asked 2021-Nov-01 at 23:32

            We have a Jenkins setup on Google Kubernetes Engine with dynamic kubernetes pods serving as build agents. I want to integrate Pylint as a build step. Python version running on kubernetes pod is 2.7.16. Any idea how to install Pylint and integrate it into Jenkins build?


            Jenkins is running on a Google Kubernetes Engine cluster.

            Kubernetes Cloud is configured in Jenkins as given below:

            List of plugins installed are as follows:



            Answered 2021-Nov-01 at 23:32

            I think you probably can achieve the desired behavior by adding a convenient container to your pod template: this container will include the necessary Pylint dependencies and will be used in addition to the default Jenkins agent image in your pod.

            As you can see in your screenshot, you can add this container when configuring your pod template and Kubernetes in the Jenkins Web console.

            In addition, you can provide the necessary information when defining your pipeline. Consider for instance the example provided in the Jenkins Kubernetes plugin documentation:



            On Debian 11 (Bullseye) /proc/self/cgroup inside a docker container does not show docker infos
            Asked 2021-Aug-31 at 22:01

            I recently updated from Debian 10 (Buster) to 11 (Bullseye) and since then my Jenkins setup inside Docker is not working anymore, as Jenkins tries to find out if it is running in a docker container by checking /proc/self/cgroup.

            Normally /proc/self/cgroup inside a docker container would look something like this:



            Answered 2021-Aug-31 at 22:01

            The change in behavior is due to that debian uses cgroups v2 starting with Debian 11/Bullseye. The docker engine itself supports cgroups v2 since v20.10.x.

            This means, as soon as you have a distribution that uses cgroups v2 and a recent version of the Docker engine, you cannot get the container id with your method.

            I've opened a similar question to find an alternative method: How to get docker container ID from within the container with cgroup v2

            The only way I know to get the id is by using the docker api, but that is not an elegant solution if you just want to know if the process runs inside a container. (And may pose a security risk if you expose the docker socket inside the container)

            For now as a workaround you could manually signal the process that it is run inside a container environment, e.g. by specifying an environment variable on container creation.



            When should you use single curly braces vs double curly braces for variable reference in github actions?
            Asked 2021-Aug-31 at 20:05

            I'm starting to learn github actions (converting from jenkins piplines). I am not super familiar with yaml.

            I cannot figure out when or why variables should be referenced using double curly braces vs single curly braces. I have a feeling there is an important distinction here.... Can you clue me in?
