# Tips & Tricks

## Kako se spojiti na https://labs.play-with-docker.com/ preko SSH

- na stranici https://labs.play-with-docker.com/ odaberite start te se prema potrebi logirajte sa google accountom



otvara se funkcionalan online terminal ali potrebno je vrijeme privikavanja


- za bolji user experiance preporuča se korištenje SSH konekcije
- potrebno je izgenerirati ključ korištenjem `ssh-keygen -f [putanja_za_snimanje]`

C:\>ssh-keygen -f c:\sshkey\sshkey

Generating public/private ed25519 key pair.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in c:\sshkey\sshkey
Your public key has been saved in c:\sshkey\sshkey.pub
The key fingerprint is:
SHA256:7lTKJGkFSd/j6wFga49ivT5zwvsXXF60WmM15vZYrfg nekiuser@DESKTOP-S4AGHC2
The key's randomart image is:
+--[ED25519 256]--+
|     .o.         |
|      .o .    .o.|
|      o o o  .ooo|
|     . = . .. *oo|
|      * S.oo *.=.|
|     + B +o.+ o .|
|    o.o * o. .   |
|   . .=+....  E  |
|     .+Bo..      |
+----[SHA256]-----+



C:\>dir c:\sshkey
 Volume in drive C has no label.
 Volume Serial Number is 6078-D3C3

 Directory of c:\sshkey

24.10.2025.  13:41    <DIR>          .
24.10.2025.  13:41               419 sshkey
24.10.2025.  13:41               105 sshkey.pub
               2 File(s)            524 bytes
               1 Dir(s)  389.894.504.448 bytes free

- na stranicama https://labs.play-with-docker.com/ kopirajte ssh link kao što je prikazano na slici


### u terminalu (CMD, PowerShell)

- potrebno je kopirati taj ssh link u terminal ALI između ssh i ip172.... upišite putanju ssh ključa: `-i [putanja_do_ssh_kljuca]`

ssh -i c:\sshkey\sshkey [e-mail]
Connecting to 40.114.80.134:8022

### korištenjem PuTTY alata

- skinite PuTTy sa stranica https://putty.org/index.html
- kako bi se isti key primjenio i u Putty potrebno je prvo prebaciti ga u format kojeg čita Putty korištenjem PuTTYgen
- pokrenite PuTTYgen




- za potrebe testiranja nije nužno postavljati passhrase (jedino ako baš želite)


- pokrenite PuTTY i dodajte ključ pod Connection > SSH > Auth > Credentials


- PRIJE nego stisnete **Open** snimite konekciju za ubuduće


- sada upišite adresu s stranice *ssh ip172-18-0-51-d3tm9qi...* ALI bez **ssh** i kliknite na **Open**
