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

Elastic Beats on pfSense : Installation and configuration

Summary Though in many cases syslog is preferred to transport the pfSense logs to external system, Elastic beats provides quite a niche way to send the logs while modelling the data alongside. This makes it ready-made to send to ElasticSearch directly and get ready-made outcomes like SIEM, performance etc. Pre-reqs A build server (preferably Ubuntu or Fedora) with internet connectivity shell access to pfsense server Basic knowledge of Elastic Stack (filebeat.yml configurations etc) Ensure connectivity is allowed from pfsense machine to your Elastic Stack receiver Setup Summary Connectivity tests Install dependencies in build server (vagrant, virtualbox, gmake, go etc) Download Elastic Beats source Make elastic Beats package for FreeBSD Copy binary packages to pfsense server Configure Beats to send to destination Configure ElasticSearch to view the data Installation Steps Connectivity tests Logon to pfsense server via Shel

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)
