Save a running docker as a new image

Save a running docker as a new image

The following will show you how to create a new docker image from a running container that you have modified. The image will only exist locally, meaning you can only access and use it on the computer you create it. It will not be associated with any container registry.

We will start with the ubuntu container image as our base.

Run and attach to a container

docker run -a stdin -a stdout -it ubuntu /bin/bash

Create PFX file from a CRT and KEY file

Create PFX file from a CRT and KEY file

Some services require a combined pfx file to provide TLS to a client

Generating the pfx file

The easiest way is to utilize openssl on the command line. Assuming you already have the .crt and .key files, run the following command.

openssl pkcs12 -export -out domain.name.pfx -inkey domain.name.key -in domain.name.crt

Generating the pfx file with root CA and intermediate certs

Fail2ban Debian-based Config

Fail2ban Configuration

The default Fail2ban installation comes with two configuration files, /etc/fail2ban/jail.conf and /etc/fail2ban/jail.d/defaults-debian.conf. It is not recommended to modify these files as they may be overwritten when the package is updated.

Fail2ban reads the configuration files in the following order. Each .local file overrides the settings from the .conf file:

  • /etc/fail2ban/jail.conf
  • /etc/fail2ban/jail.d/*.conf
  • /etc/fail2ban/jail.local
  • /etc/fail2ban/jail.d/*.local
