1.2.7 authorization-mode argument is not set to AlwaysAllow FAIL
1.2.8 authorization-mode argument includes Node FAIL
1.2.7 authorization-mode argument includes RBAC FAIL
Fix all of the following violations that were found against the Kubelet:

Follow the documentation and create Pod Security Policy objects as per your environment.
Then, edit the API server pod specification file $apiserverconf
on the master node and set the --enable-admission-plugins parameter to a value that includes PodSecurityPolicy :
--enable-admission-plugins=...,PodSecurityPolicy,...
Then restart the API Server.

Follow the Kubernetes documentation and setup the TLS connection between the apiserver and kubelets. Then, edit the API server pod specification file
$apiserverconf on the master node and set the --kubelet-certificate-authority parameter to the path to the cert file for the certificate authority.
--kubelet-certificate-authority=<ca-string>
scored: true
Fix all of the following violations that were found against the ETCD:-
a. Ensure that the --auto-tls argument is not set to true
Edit the etcd pod specification file $etcdconf on the master node and either remove the --auto-tls parameter or set it to false. --auto-tls=false b. Ensure that the --peer-auto-tls argument is not set to true Edit the etcd pod specification file $etcdconf on the master node and either remove the --peer-auto-tls parameter or set it to false. --peer-auto-tls=false


質問 # 50
Before Making any changes build the Dockerfile with tag base:v1
Now Analyze and edit the given Dockerfile(based on ubuntu 16:04)
Fixing two instructions present in the file, Check from Security Aspect and Reduce Size point of view.
Dockerfile:
FROM ubuntu:latest
RUN apt-get update -y
RUN apt install nginx -y
COPY entrypoint.sh /
RUN useradd ubuntu
ENTRYPOINT ["/entrypoint.sh"]
USER ubuntu
entrypoint.sh
#!/bin/bash
echo "Hello from CKS"
After fixing the Dockerfile, build the docker-image with the tag base:v2

  • A. To Verify: Check the size of the image before and after the build.

正解:A
