[Docker]

Docker is an open platform for developing, shipping, and running applications. It is the standard de facto for packaging and sharing apps – from desktop to the cloud.

To achieve its goal, Docker is using containers.

The container has the following characteristics:

  • A container is a package for the software and all required libraries.
  • As soon as is launched, a container determines a runtime environment for your application.
  • A container is lighter than a virtual machine, so that it can be launched way faster.
  • A container is distributed in the form of an image, which consists of multiple layers. Multiple containers can reuse these layers.

[OpenVPN] Multi-TAP

OpenVPN, by default, installs only one TAP network interface. If you want to connect to multiple VPNs simultaneously you need a TAP interface for each VPN.

Add an additional TAP adapter

  • Open a command prompr with administrative rights
  • Go to the TAP install folder C:\Program Files\TAP-Windows\bin
  • Launch the addtap.bat script, the result will be : 
    "devcon.exe" install "C:\Program Files\TAP-Windows\driver\OemWin2k.inf" tap0901

Device node created. Install is complete when drivers are installed...

[HSQLDB] How to connect with Spring Boot app

In-memory database

For connecting to in-memory HSQL database, we need to launch a db browser in the same JVM instance.

First, we need to add the following code in a Configuration class of the Spring application.

    @PostConstruct
    public void startDBManager() {
        //hsqldb
        DatabaseManagerSwing.main(new String[] { "--url", "jdbc:hsqldb:mem:testdb", "--user", "sa", "--password", "" });
 }

Vagrant

Error

If an error 'initialize': negative string size (or size too big) occurs, the solution is to remove the index file in ~\.vagrant.d\data\machine-index

Disk size

Vagrant doesn’t provide any out-of-the-box option to configure or to change the disk size. The disk size of a VM totally depends on the base image used for the VM. Moreover, most Vagrant boxes use VMDK disks which cannot be resized!

vagrant-disksize plugin

This plugin allows to resize the disk size.
