How to generate static (HTML) documentation from a JSON/YAML Swagger file?

1. Go to: http://editor.swagger.io
2. Choose from top left menu: File → Import file
3. Import your JSON/YAML description file
4. Choose from top menu: Generate Client → html2 (“html2” looks a lot nicer and is more functional than “html”)
5. You will be prompted with a zip file download which includes that static content (including an index.html file that has all the data)

Igasugune ssh ligipääs käib Elionis tänapäeval ybershell.estpak.ee kaudu. Selleks, et seda võimalikult mugav kasutada oleks kogume siia alla häid näpunäiteid.

Nii nagu igas masinas on ka yberis mõistlik kasutada alias'i, et kiirelt ja lihtsalt jõuda sealt edasi kuhu vaja. Selleks, et aliased toimiks tuleb need kirjutada kodukataloogi .bashrc faili (vim ~/.bashrc). List aliastest, mida näiteks nutiTV inimesed võivad kasutada:

alias devel='ssh rene@194.126.108.195'
alias dtv_controller='ssh erki@194.126.108.216'
alias dtvapi1='ssh dtvmw@194.126.108.210'
alias dtvdevelapi='ssh dtvmw@develapi.mw.elion.ee'
alias logger='ssh 88.196.0.29'
alias stbmng='ssh stbmng.dtv.elion.ee'
alias web1='ssh dtvmw@194.126.108.221'
alias web2='ssh dtvmw@194.126.108.222'
alias web4='ssh dtvmw@194.126.108.194'
alias web5='ssh dtvmw@194.126.108.205'
alias web6='ssh dtvmw@194.126.108.208'
alias web7='ssh dtvmw@194.126.108.211'
alias web8='ssh dtvmw@194.126.108.212'
alias web9='ssh dtvmw@194.126.108.213'

Kui lisad uue aliase, siis pead selle rakendumiseks tegema (source ~/.bashrc) või yberist korra välja logima.

Väga mõistlik on korra kätte võtta ja oma ssh public key sihtkoha masinatesse panna, et edasipdi alati kiirelt ilma parooli trükkimata neisse sisse saada.

Selleks pead kõigepealt oma masinas endale võtmepaari genereerima (kasuta tühja passphrase'i):

ssh-keygen -t rsa -b 2048

Nüüd võta enda masina kodukataloogist enda avalik võti:

vim ~/.ssh/id_rsa.pub

… ja kleebi see nendesse masinatesse kuhu ilma parooli tagumata (ssh võtmega) soovid edaspidi sisse saada .Paljudes masinates on authorized_keys fail juba olemas, siis pane enda võti sinna viimasele reale juurde. Kui faili pole, siis tee see. Vaata, et su võtmes kopeerimise tulemusel reavahetusi sees ei oleks:

vim ~/.ssh/authorized_keys

Eimesena pead oma avaliku võtme yberisse panema. Ja edasi siis kõgisse järgmistesse. NB! Alati pead kasutama enda masinas genereeritud avalikku võtit. yberis uusi võtmeid genereerida ei tohi!

Kui pärast avaliku võtme lisamist mõnda masinasse sinna sisse logimisel ikka passi küsitakse, siis tee seal:

chmod u+x ~/.ssh

Selleks, et sama võtmega ka yberist edasi saaks liikuda pead kõigepealt enda masinas käivitama ssh-agent'i (vt. all olevat peatükki) ning yberisse logides alati kasutama ssh võtit -A (ssh -A ybershell.estpak.ee).

Iga normaalne inimene kasutab yberis screen'i ;)

Kuigi screen'i mõte ongi koguaeg valmis ja ootel olla, siis esmakordsel kasutamisel tuleb ta luua ning kui yberile buuti tehakse, siis paraku tuleb ta ka uuesti luua. Seega elu lihtsustamiseks on üsna mõistlik luua screeni conf, mis käivitamisel juba sinu eest õigete nimedega õiged aknad lahti võtab. Ning kui oled ssh-key'ga autentimise kõikjal käima ajanud (vt. eelmist punkti), siis võtab ta kohe ka ssh'd kõigisse vajalikesse kohtadesse üles.

Selle saavutamiseks võta yberis lahti enda screeni confi fail:

vim ~/.screenrc

ning koosta endale sobiv conf selle näite alusel (screen -t ”<akna nimi>” <akna number> <käsk, mis aknas käivitada>):

screen -t "SQL new MW (web4)" 1 ssh dtvmw@194.126.108.194
screen -t "SQL VOD" 2 ssh dtvmw@194.126.108.210
screen -t "SQL devel MW" 3 ssh 194.126.108.195
screen -t "SQL dhcp" 4 ssh dtvmw@194.126.108.210
screen -t "logger" 5 ssh 88.196.0.29
screen -t "stbmng" 6 ssh stbmng.dtv.elion.ee
screen -t "MW API" 7 ssh dtvmw@194.126.108.210
screen -t "devel MW API" 8 ssh dtvmw@develapi.mw.elion.ee
screen -t "web1" 9 ssh dtvmw@194.126.108.221
screen -t "web2" 10 ssh dtvmw@194.126.108.222
screen -t "yber" 11

Enne kui seda screen'i looma hakkad vaata üle:

1. kas sul aliased on ilusti paigas (muid pead lisamisel pärast eraldi igas screeni aknas need aktiveerima)
2. kas oled oma ssh avalikud võtmed kõigisse soovitud masinattes kopeerinud
3. kas sul enda masinas ssh-agent käib ning oled yberisse loginud -A võtmega. Selleks käivita yberis käsk: ssh-add -L

Kui kõik eelnev korras ja nüüd lihtsalt screen käsuga screeni käivitad, siis tehakse sulle kohe 11 aknaga screen, kus on ilusti olemas juba mõistlike nimedega ja sisse logitud ssh sessioonid vajalikesse kohtadesse.

Edaspidi kui soovid seda screeni yberis külge võtta, siis nagu ikka teed lihtsalt screen -rd

Näide ssh-agendi kasutamisest. Kõigepealt pead enda masinas ssh-agendi tööle panema:

spirit@kriszi-l:~$ ssh-agent

SSH_AUTH_SOCK=/tmp/ssh-HDwqLP9643/agent.9643; export SSH_AUTH_SOCK;
SSH_AGENT_PID=9644; export SSH_AGENT_PID;
echo Agent pid 9644;

spirit@kriszi-l:~$ ssh-add

Enter passphrase for /home/spirit/.ssh/id_rsa:
Identity added: /home/spirit/.ssh/id_rsa (/home/spirit/.ssh/id_rsa)

ssh'ga yberisse logimisel peab alati -A v6ti kaasas olema, et agendi conf kaasa liiguks
spirit@kriszi-l:~$ ssh -A ybershell.estpak.ee

nüüd logi ssh'ga ybershelli sisse ja kontrolli alljärgneva käsuga, kas sinu key on kaasas:
spirit@uus-ybershell:~$ ssh-add -L
