apk add --no-cache cfdisk e2fsprogs-extra

How to add a custom trusted certificate for making HTTP requests against external sites

Thoughts on how to add trusted store for connection to external sites that use that certificate for HTTPS

Option 1: global configuration

One can just provide the -Djavax.net.ssl.trustStore=<path/to/store> -Djavax.net.ssl.trustStorePassword=<password> options when running the Java application

However, this is not always possible (for example, when run in the cloud).

And if you want to use server.ssl.trust-store/server.ssl.trust-store-password options from Spring Boot, be aware that with those you also have to provide key-store options as well. And, basically that would be an abuse, because this configuration is specifically for server side of your application.

Add CA cert to local trust store on CentOS, Manjaro, Debian or Ubuntu
  • Open a webpage that uses the CA with Firefox
  • Click the lock-icon in the addressbar -> show information -> show certificate
  • the certificate viewer will open
  • click details and choose the certificate of the certificate-chain, you want to import to CentOS
  • click "Export..." and save it as .crt file
  • Copy the .crt file to /etc/pki/ca-trust/source/anchors on your CentOS machine
  • run update-ca-trust extract
  • test it with wget https://example.com

On Manjaro (arch) the location for the certificates is: /usr/share/ca-certificates/trust-source/anchors (low priority) or /etc/ca-certificates/trust-source/anchors/ (high priority) and the command to update is update-ca-trust extract.

Enable TCP port 2375 for external connection to Docker

Enable TCP port 2375 for external connection to Docker

See this issue.
Docker best practise to Control and configure Docker with systemd.

  1. Create daemon.json file in /etc/docker:

     {"hosts": ["tcp://0.0.0.0:2375", "unix:///var/run/docker.sock"]}

Docker Swarm Port Requirements, both Swarm Mode 1.12+ and Swarm Classic, plus AWS Security Group Style Tables

Docker Swarm Mode Ports

Starting with 1.12 in July 2016, Docker Swarm Mode is a built-in solution with built-in key/value store. Easier to get started, and fewer ports to configure.

Inbound Traffic for Swarm Management

  • TCP port 2377 for cluster management & raft sync communications
  • TCP and UDP port 7946 for "control plane" gossip discovery communication between all nodes
  • UDP port 4789 for "data plane" VXLAN overlay network traffic
  • IP Protocol 50 (ESP) if you plan on using overlay network with the encryption option

AWS Security Group Example
