P\u0159ejdeme k j\u00e1dru<\/b>. Inspirov\u00e1na \u010dl\u00e1nkem <\/a><\/noindex> Jurijem Emeljjanovem o mo\u017enostech Apache Airflow v oblasti automatizace analytick\u00fdch postup\u016f, jsem se rozhodla za\u010d\u00edt pou\u017e\u00edvat nab\u00edzenou sadu knihoven ve sv\u00e9 pr\u00e1ci. T\u011bm, kdo s Apache Airflow je\u0161t\u011b nejsou v\u016fbec obezn\u00e1meni, by mohla b\u00fdt zaj\u00edmav\u00e1 mal\u00e1 p\u0159ehledov\u00e1 neaktu\u00e1ln\u00ed statistika <\/a><\/noindex> na webu N\u00e1rodn\u00ed knihovny N.

\nProjdeme si kroky instrukce (spoiler \u2014 5. krok prob\u00edhal bez probl\u00e9m\u016f):<\/p>\n

1. Instalace Windows Subsystem for Linux pro n\u00e1slednou instalaci distribuc\u00ed Linuxu<\/b><\/p>\n

To je men\u0161\u00ed z probl\u00e9m\u016f, jak se \u0159\u00edk\u00e1: <\/p>\n

Ovl\u00e1dac\u00ed panel \u2192 Programy \u2192 Programy a funkce \u2192 Povolen\u00ed a zak\u00e1z\u00e1n\u00ed funkc\u00ed Windows \u2192 Windows Subsystem for Linux<\/p>\n

2. Instalace vybran\u00e9 linuxov\u00e9 distribuce<\/b><\/p>\n

Pou\u017eila jsem aplikaci Ubuntu<\/a><\/noindex>.<\/p>\n

3. Instalace a aktualizace pip <\/b><\/p>\n

sudo apt-get install software-properties-common\nsudo apt-add-repository universe\nsudo apt-get update\nsudo apt-get install python-pip<\/code><\/pre>\n
\n4. Instalace Apache Airflow<\/b><\/p>\n
export SLUGIFY_USES_TEXT_UNIDECODE=yes\npip install apache-airflow<\/code><\/pre>\n
\n5. Inicializace datab\u00e1ze<\/b><\/p>\n
A pr\u00e1v\u011b zde za\u010daly m\u00e9 mal\u00e9 pot\u00ed\u017ee. Instrukce p\u0159ikazuje zadat p\u0159\u00edkaz airflow initdb<\/code> a p\u0159ej\u00edt k dal\u0161\u00edmu kroku. Nicm\u00e9n\u011b jsem neust\u00e1le dost\u00e1vala odpov\u011b\u010f airflow: command not found<\/code>. Je logick\u00e9 p\u0159edpokl\u00e1dat, \u017ee do\u0161lo k probl\u00e9m\u016fm b\u011bhem instalace Apache Airflow a jednodu\u0161e chyb\u00ed pot\u0159ebn\u00e9 soubory. Po ujist\u011bn\u00ed, \u017ee je v\u0161e na spr\u00e1vn\u00e9m m\u00edst\u011b, jsem se rozhodla zkusit uv\u00e9st \u00faplnou cestu k souboru airflow (m\u011blo by to vypadat takto: \u00fapln\u00e1\/cesta\/k\/souboru\/airflow initdb<\/code>). Ale z\u00e1zrak se nekonal a odpov\u011b\u010f byla stejn\u00e1 airflow: command not found<\/code>. Zkusila jsem pou\u017e\u00edt relativn\u00ed cestu k souboru (.\/.local\/bin\/airflow initdb<\/code>), co\u017e vedlo k objeven\u00ed nov\u00e9 chyby ModuleNotFoundError: No module named json'<\/code>, kterou lze p\u0159ekonat aktualizac\u00ed knihovny werkzeug<\/i> (v m\u00e9m p\u0159\u00edpad\u011b na verzi 0.15.4):<\/p>\n
pip install werkzeug==0.15.4<\/code><\/pre>\n
\nV\u00edce o werkzeug si m\u016f\u017eete p\u0159e\u010d\u00edst zde<\/a><\/noindex>. <\/p>\n
Po t\u00e9to jednoduch\u00e9 manipulaci byl p\u0159\u00edkaz .\/.local\/bin\/airflow initdb<\/code> prov\u00e1d\u011bn \u00fasp\u011b\u0161n\u011b. <\/p>\n
6. Spu\u0161t\u011bn\u00ed serveru Airflow<\/b><\/p>\n
T\u00edmto obt\u00ed\u017ee s p\u0159\u00edstupem k airflow je\u0161t\u011b neskon\u010dily. Spu\u0161t\u011bn\u00ed p\u0159\u00edkazu .\/.local\/bin\/airflow webserver -p 8080<\/code> vedlo k chyb\u011b No such file or directory<\/code>. Pravd\u011bpodobn\u011b by zku\u0161en\u00fd u\u017eivatel Ubuntu ihned zkusil p\u0159ekonat tyto pot\u00ed\u017ee s p\u0159\u00edstupem k souboru pomoc\u00ed p\u0159\u00edkazu export PATH=$PATH:~\/.local\/bin\/<\/code> (tedy p\u0159id\u00e1n\u00edm katalogu \/.local\/bin\/ k existuj\u00edc\u00ed cest\u011b hled\u00e1n\u00ed spustiteln\u00fdch soubor\u016f, definovan\u00e9 prom\u011bnnou PATH), ale tento p\u0159\u00edsp\u011bvek je ur\u010den pro ty, kte\u0159\u00ed p\u0159ev\u00e1\u017en\u011b pracuj\u00ed s Windows a mo\u017en\u00e1 pova\u017euj\u00ed toto \u0159e\u0161en\u00ed za nep\u0159ehledn\u00e9. <\/p>\n
Po v\u00fd\u0161e popsan\u00e9 manipulaci byl p\u0159\u00edkaz .\/.local\/bin\/airflow webserver -p 8080<\/code> \u00fasp\u011b\u0161n\u011b proveden.<\/p>\n
7. URL: localhost<\/noindex>:8080\/<\/b><\/p>\n
Pokud v\u0161e prob\u011bhlo \u00fasp\u011b\u0161n\u011b v p\u0159edchoz\u00edch kroc\u00edch, jste p\u0159ipraveni dob\u00fdt analytick\u00e9 vrcholy.<\/p>\n
Douf\u00e1m, \u017ee v\u00fd\u0161e popsan\u00e1 zku\u0161enost s instalac\u00ed Apache Airflow na Windows 10 bude u\u017eite\u010dn\u00e1 za\u010d\u00ednaj\u00edc\u00edm u\u017eivatel\u016fm a urychl\u00ed jejich vstup do sv\u011bta modern\u00edch analytick\u00fdch n\u00e1stroj\u016f. <\/p>\n
P\u0159\u00ed\u0161t\u011b bych r\u00e1da pokra\u010dovala v t\u00e9matu a pod\u011blila se o zku\u0161enosti s pou\u017e\u00edv\u00e1n\u00edm Apache Airflow v oblasti anal\u00fdzy chov\u00e1n\u00ed u\u017eivatel\u016f mobiln\u00edch aplikac\u00ed.
