Wow, SSHD on Synology - fun and games

 Having created a new user on my Synology DS414+, I was trying/failing to SSH using a non-admin user, via the command: -

ssh hayd@diskstation

I kept getting asked for a password, even though I was expecting to authenticate using my private key, having added my public key to the ~/.ssh/authorized_keys file on the NAS.

After lots of digging using ssh -vvv etc., I saw this: -

...

debug3: send packet: type 50

debug2: we sent a publickey packet, wait for reply

debug3: receive packet: type 51

debug1: Authentications that can continue: publickey,password

debug2: we did not send a packet, disable method

debug3: authmethod_lookup password

debug3: remaining preferred: ,password

debug3: authmethod_is_enabled password

debug1: Next authentication method: password

hayd@diskstation's password: 

...

which led me down a path of checking permissions to the user's home directory.

Firstly, I changed the permission of the .ssh subdirectory: -

chmod 700 /var/services/homes/hayd/.ssh/

but no dice.

Secondly, I changed the permission of the authorized_keys file: -

chmod 600 /var/services/homes/hayd/.ssh/authorized_keys 

Still nada.

Thirdly, I changed the permission of the home directory itself: -

chmod g-w /var/services/homes/hayd/

C'est voila.

Sigh!

New day, new Docker, new capability - image scanning

 Whilst I was upgrading some of my Ubuntu boxes the other day, I noticed a new plugin - docker-scan-plugin - in the list of things being upgraded.

A quick Google brought me this: -

Vulnerability scanning for Docker local images

Having since upgraded Docker on my Mac: -

tekton-lint   latest    b79680846c0c   10 days ago   93.1MB

and then scanned one of them: -

docker scan busybox

Docker Scan relies upon access to Snyk, a third party provider, do you consent to proceed using Snyk? (y/N)
y

✓ Tested busybox for known vulnerabilities, no vulnerable paths found.

Note that we do not currently have vulnerability data for your image.

Definitely a nice capability to have in the kitbag - we're also using IBM Container Registry's built-in Vulnerability Advisor tool, but more insights are better than fewer ....

Penny dropped - why is my job immutable ?

I'm tinkering with kube-bench at present, and wanted to deploy it as a Kubernetes Job using the job.yaml that's included with the repo.

However, my custom-built kube-bench image is stored in a private registry ( via IBM Container Registry ) so I needed to reference a Kubernetes Secret which I'd previously defined within my K8s cluster.

So far, so good ...

Having defined the Secret, I needed to reference it in the Job description ( job.yaml ) via an imagePullSecrets which I'd added to the YAML: -

---
apiVersion: batch/v1
kind: Job
metadata:
  name: kube-bench
spec:
  template:
    metadata:
      labels:
        app: kube-bench
    spec:
      hostPID: true
      imagePullSecrets:
        - name: mysecret
      containers:
        - name: kube-bench
          image: aquasec/kube-bench:latest
          command: ["kube-bench"]

However, when I tried to apply the YAML: -

kubectl apply -f job.yaml 

The Job "kube-bench" is invalid: spec.template: Invalid value: core.PodTemplateSpec{ObjectMeta:v1.ObjectMeta{Name:"", GenerateName:"", Namespace:"", SelfLink:"", UID:"", ResourceVersion:"",

What the heck ?

Then I read this: -


which says, in part: -

This is not a bug, you can't change the template after the job has been created.

Ah!!!

I listed my jobs: -

kubectl get jobs -A

NAMESPACE          NAME                                                  COMPLETIONS   DURATION   AGE
default            kube-bench                                            0/1           117m       117m
tekton-pipelines   pw-3282a77a-680d-4731-a3f0-6c73f67ddb42-cleaner-job   0/1           6d20h      6d20h
tekton-pipelines   pw-54d9eabf-ade2-47ae-bfa1-d1b7b3be2240-cleaner-job   0/1           6d20h      6d20h

So the job already exists - so how can I change the job description for an inflight job ?
