Thanks Laurent. It is working now. For future reference I will 
write all steps here.

This guide assumes DMD is installed using the install script:

curl -fsS https://dlang.org/install.sh | bash -s dmd
~/dlang/install.sh install dmd
~/dlang/install.sh install ldc

If you want to permanently set PATH and other needed variables 
you need to copy them from activate script of one of installed 
compilers into your .profile file. If you are on KDE then it 
should go in ~/.config/plasma-workspace/env/ldc.sh. This is how 
my ldc.sh looks like since I have KDE and I want ldc compiler by 
default:

# set PATH so it includes LDC compiler
if [ -d "$HOME/dlang/ldc-1.10.0" ] ; then
         PATH="$HOME/dlang/ldc-1.10.0/bin${PATH:+:}${PATH:-}"
         export PATH="$HOME/git/workspace-d/bin${PATH:+:}${PATH:-}"
         export 
LIBRARY_PATH="$HOME/dlang/ldc-1.10.0/lib${LIBRARY_PATH:+:}${LIBRARY_PATH:-}"
         export 
LD_LIBRARY_PATH="$HOME/dlang/ldc-1.10.0/lib${LD_LIBRARY_PATH:+:}${LD_LIBRARY_PATH:-}"
         export DMD=ldmd2
         export DC=ldc2
fi

After that install VSCode if it is not already installed. Open it 
and go to Extensions tab (last icon on the left). Search for 
"webfreak". You will see "D Language utility extension pack" 
which contains all you need for the DLang development. In the 
description you can see what individual plugins it installs and 
what they do so if you choose you can only install some of them. 
"D Programming Language (code-d)" is required for autocomplete 
and "Native Debug" for debugging. Once you install that and 
reload VSCode go to File-Preferences-Settings (Ctrl+,). In the 
right part of the window, under User Settings you will see some 
dlang settings are already added. Bellow them I also added this:

     "d.dmdPath": "ldmd2",
     "d.stdlibPath": [
         "/home/igors/dlang/dmd-2.081.1/druntime/import",
         "/home/igors/dlang/dmd-2.081.1/phobos"
     ],

First line is needed because I want to use LDC compiler. After 
that you can open View-Command Pallete (Ctrl+Shift+P) and type 
code-d and see all kind of commands related to it and one of them 
should be "Create new project". This will init your project with 
a single d code file and basic dub configuration for building it. 
If at that point you press F5 you will be offered to add a GDB 
(or LLDB if you have clang installed) configuration for 
debugging. Once you do that you will get a launch.json file under 
.vscode dir in your project and there you should add this line:

"preLaunchTask": "buildAndRun",

After that you should select Tasks-Configure Tasks and in the 
drop down select dub: Run option. That will create a tasks.json 
file for building and running your project. You should add this 
line so launch.json can reference it:

"identifier": "buildAndRun",

If at this point you press F5 to debug your program it will be 
built but debugger will probably report an error how it couldn't 
find what to debug. You need to see where you program was build 
(by default in the root of your project) and then put its name in 
launch.json under target property. For example my project is 
called dtest so I set it up like this:

"target": "./dtest",

At this point it should be clear what goes where and how it works 
so you can now edit your json files and configure them to your 
liking.
