You need to create a bitbucket user that will be added to your project and has at least READ permissions, add this user to Jenkins credentials (username/pw). The plugin uses the bitbucket API to do everything.

Under Configure System look for Bitbucket Endpoints and enable "Manage Hooks"

The webhook address is: https://your.jenkins.tld/bitbucket-scmsource-hook/notify/

[Kubernetes] How to create a new restricted RBAC user in Kubernetes 1.9

1. connect to any master node and get the ca.pem and ca-key.pem from /etc/kubernetes/ssl
2. create new user, in this example we call this user "testuser"

3. openssl genrsa -out testuser.key 2048
   openssl req -new -key testuser.key -out testuser.csr -subj "/CN=testuser/O=testuser"
   openssl x509 -req -in testuser.csr -CA ca.pem -CAkey ca-key.pem -CAcreateserial -out testuser.crt -days 500

4. create role-deployment-manager.yaml :

     kind: Role
     apiVersion: rbac.authorization.k8s.io/v1beta1
     metadata:
       namespace: office
       name: deployment-manager
     rules:
     - apiGroups: ["", "extensions", "apps"]
       resources: ["deployments", "replicasets", "pods"]
       verbs: ["get", "list", "watch", "create", "update", "patch", "delete"] # You can also use ["*"]

     
5. create rolebinding-deployment-manager.yaml

kind: RoleBinding
  apiVersion: rbac.authorization.k8s.io/v1beta1
  metadata:
    name: deployment-manager-binding
    namespace: office
  subjects:
  - kind: User
    name: testuser
    apiGroup: ""
  roleRef:
    kind: Role
    name: deployment-manager
    apiGroup: ""




6. $kubectl config set-credentials testuser --client-certificate=/home/testuser/.certs/testuser.crt  --client-key=/home/testuser/.certs/testuser.key
   $kubectl config set-context testuser-context --cluster=testcluster --namespace=office --user=testuser

7.  kubectl create -f both files and then test with kubectl --context=testuser-context get pods, confirm restriction by changing adding -ndefault to see if default namespace access is denied
