How to Assign a Static IP to a Docker Container

 Ref: https://www.howtogeek.com/devops/how-to-assign-a-static-ip-to-a-docker-container/

Setting Up Static IPs

First, you’ll need to set up a Docker network, and since we care about the IP address, you’ll need to specify a fixed subnet:

docker network create --subnet=172.20.0.0/16 customnetwork

Then, you can run a container, specifying the network with the --net flag, and specifying the IP with the -ip flag:

docker run --net customnetwork --ip 172.20.0.10 -d container

[NODEJS] Covert wiki text to html

[Html] What's the correct way to display multi line text?

Ref: https://stackoverflow.com/questions/10937218/how-to-show-multiline-text-in-a-table-cell 

You want to use the CSS white-space:pre applied to the appropriate <td>. To do this to all table cells, for example:

td { white-space:pre }

Alternatively, if you can change your markup, you can use a <pre> tag around your content. By default web browsers use their user-agent stylesheet to apply the same white-space:pre rule to this element.

The PRE element tells visual user agents that the enclosed text is "preformatted". When handling preformatted text, visual user agents:

• May leave white space intact.
• May render text with a fixed-pitch font.
• May disable automatic word wrap.
• Must not disable bidirectional processing.

Package 'mysql-client' has no installation candidate in php-fpm image build using docker compose

Ref: https://stackoverflow.com/questions/57048428/e-package-mysql-client-has-no-installation-candidate-in-php-fpm-image-build-u

 php:7.3-fpm now use Debian 10 (Buster) as its base image and Buster ships with MariaDB, so just replace mysql-client with mariadb-client should fix it.
