Kubernetes & n8n: Setup n8n using K8S (Part 2) with TLS/https

 

Kubernetes & n8n: Setup n8n using K8S (Part 2)

Summary

We have briefly discussed on automating various tasks using n8n and installation of n8n within Kubernetes in Part1. In this part, we mostly concentrate on how to enable TLS (for https) and terminate before it hits n8n

Pre-Reqs

  • Setting up of n8n in Kubernetes ; Read Part1
  • Knowledge of TLS, certificates

Summary Steps

  • Ensure n8n is configured properly with by http
  • Implement Kubernetes Ingress with https
  • There are two options from here
    1. End to end TLS by redirecting proxy to n8n 
    2. TLS termination at proxy and private network to be non-secure
  • We follow the second option as it is easier, thus creating Ingress and pointing to n8n service

Steps

Steps in lab_server

  • Ensure Certificate is created and implemented as a secret in Kubernetes preferably in same namespace
kubectl -n n8n create secret tls tls-secret --key test.key --cert test.crt

  • Use the same tls-secret in the Ingress config
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: n8n-ingress
spec:
  tls:
    - hosts:
      - n8n.mydev.test
      secretName: tls-secret
  rules:
  - host: n8n.mydev.test
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: n8n
            port:
              number: 5678

Syslog Standards: A simple Comparison between RFC3164 & RFC5424

Syslog Standards: A simple Comparison between RFC3164 (old format) & RFC5424 (new format) Though syslog standards have been for quite long time, lot of people still doesn't understand the formats in detail. The original standard document is quite lengthy to read and purpose of this article is to explain with examples Some of things you might need to understand The RFC standards can be used in any syslog daemon (syslog-ng, rsyslog etc.) Always try to capture the data in these standards. Especially when you have log aggregation like Splunk or Elastic, these templates are built-in which makes your life simple. Syslog can work with both UDP & TCP  Link to the documents the original BSD format ( RFC3164 ) the “new” format ( RFC5424 ) RFC3164 (the old format) RFC3164 originated from combining multiple implementations (Year 2001)

VS Code & Portable GIT shell integration in Windows

Visual Studio Code & GIT Portable shell Integration Summary Many of your corporate laptop cannot install programs and it is quite good to have them as portable executables. Here we find a way to have Portable VS Code and Portable GIT and integrate the GIT shell into VS Code Pre-Reqs VS Code (Install version or Portable ) GIT portable Steps Create a directory in your Windows device (eg:  C:\installables\ ) Unpack GIT portable into the above directory (eg it becomes: C:\installables\PortableGit ) Now unpack Visual Studio (VS) Code and run it. The default shell would be windows based Update User or Workspace settings of VS Code (ShortCut is:  Control+Shift+p ) Update the settings with following setting { "workbench.colorTheme": "Default Dark+", "git.ignoreMissingGitWarning": true, "git.enabled": true, "git.path": "C:\\installables\\PortableGit\\bin\\git.exe", "terminal.integrated.shell.windows"
