🥇JUnit i GitLab CI me Kubernetes

Ahakoa te mea e tino mohio ana te katoa he mea nui, he mea tika hoki te whakamatautau i to rorohiko, a he maha nga mea kua mahi aunoa mo te wa roa, i roto i te whanuitanga o Habr karekau he tohutaka kotahi mo te whakatuu huinga o aua hua rongonui i roto tenei kohanga hei (ta maatau tino pai) GitLab me JUnit . Kia whakakiia tenei waahi!

Whakataki

Tuatahi, me hoatu e ahau etahi horopaki:

I te mea ko o maatau tono katoa kei runga i nga Kubernetes, ka whakaarohia e maatau nga whakamatautau mo nga hanganga tika.
Mo te huihuinga me te tohatoha ka whakamahia e matou werf (i runga i nga waahanga hangahanga, ko te tikanga ano kei te uru a Helm).
E kore ahau e haere ki nga korero mo te hanga o nga whakamatautau: i roto i ta maatau keehi, ka tuhia e te kaihoko nga whakamatautau ia ia ano, a ka whakarite noa matou i to raatau whakarewatanga (me te aroaro o te ripoata e pa ana ki te tono hanumi).

He aha te ahua o te raupapa mahi?

Te hanga i te tono - ka waiho e matou te whakaahuatanga o tenei waahanga.
Tukuna te tono ki tetahi mokowāingoa motuhake o te kāhui Kubernetes ka timata ki te whakamatautau.
Te rapu mo nga taonga toi me te tarai i nga purongo JUnit me GitLab.
Te muku i te mokowāingoa i hangaia i mua.

Inaianei - ki te whakatinanatanga!

GitLab CI

Me timata ma te wahanga .gitlab-ci.yaml, e whakaahua ana i te tohatoha i te tono me te whakahaere i nga whakamatautau. Ko te rarangi i puta he tino puhoi, no reira i tino taapirihia ki nga korero:

Inaianei kei te raarangi .helm/templates me hanga YAML me Job - tests-job.yaml — ki te whakahaere i nga whakamatautau me nga rauemi Kubernetes e hiahiatia ana. Tirohia nga whakamaramatanga i muri i te raarangi:

He aha te momo rauemi whakaahuatia i roto i tenei whirihoranga? I te wa e tohatoha ana, ka hangaia e matou he mokowā ingoa ahurei mo te kaupapa (kua tohuhia tenei ki roto .gitlab-ci.yaml - tests-${CI_COMMIT_REF_SLUG}) ka hurihia ki waho:

Mahere Whirihora me te tuhinga whakamatautau;
Job me te whakamaarama o te peera me te tohutohu kua tohua command, ka whakahaere noa i nga whakamatautau;
PV me te PVC, ka taea e koe te rokiroki raraunga whakamatautau.

Kia whai whakaaro ki te huru whakataki ki if i te timatanga o te whakaaturanga - na reira, me takai etahi atu konae YAML o te tūtohi Helm me te tono. whakamuri hoahoa kia kore e tukuna i te wa o te whakamatautau. Koina:

{{- if ne .Values.global.run_tests "yes" }}
---
я другой ямлик
{{- end }}

Heoi, mena ko nga whakamatautau me hiahia etahi hanganga (hei tauira, Redis, RabbitMQ, Mongo, PostgreSQL...) - ka taea o raatau YAML e kore whakaweto. Hoatuhia ki roto i te taiao whakamatautau ... whakatikahia kia rite ki taau e pai ai, o te akoranga.

Tapa whakamutunga

No te mea te huihuinga me te tohatoha ma te whakamahi i nga mahi werf mo tenei wa anake i runga i te tūmau hanga (me te gitlab-runner), ka whakarewahia te pod me nga whakamatautau ki runga i te rangatira, me hanga e koe he whaiaronga. /mnt/tests i runga i te rangatira ka hoatu ki te kai oma; hei tauira, mā NFS. He tauira taipitopito me nga whakamarama ka kitea i roto K8s tuhinga.

Ko te hua ka:

user@kube-master:~$ cat /etc/exports | grep tests
/mnt/tests    IP_gitlab-builder/32(rw,nohide,insecure,no_subtree_check,sync,all_squash,anonuid=999,anongid=998)

user@gitlab-runner:~$ cat /etc/fstab | grep tests
IP_kube-master:/mnt/tests    /mnt/tests   nfs4    _netdev,auto  0       0

Karekau he tangata e aukati i te hanga tiritiri NFS tika ki runga i te gitlab-runner, katahi ka whakairihia ki roto i nga poro.

parau

Kei te patai pea koe he aha i whakararu ai i nga mea katoa ma te hanga Hopa mena ka taea e koe te whakahaere i tetahi tuhinga me nga whakamatautau tika ki runga i te kaikawe anga? He iti noa te whakautu...

Ko etahi o nga whakamatautau me uru ki te hanganga (MongoDB, RabbitMQ, PostgreSQL, me etahi atu) hei manatoko kei te mahi tika. Ka whakakotahihia e matou nga whakamatautau - na tenei huarahi, ka ngawari ki te whakauru i etahi atu hinonga. I tua atu i tenei, ka whiwhi tatou paerewa huarahi tohatoha (ahakoa te whakamahi i te NFS, te taapiri atu o nga raarangi whaiaronga).

hua

He aha ta tatou e kite ina tono tatou i te whirihoranga kua whakaritea?

Ka whakaatuhia e te tono hanumi nga tatauranga whakarāpopototanga mo nga whakamatautau e whakahaerehia ana i roto i tana paipa hou:

Ka taea te paato i ia hapa ki konei mo nga taipitopito:

NB: Ka kite te kaipanui whakarongo kei te whakamatautauhia e matou he tono NodeJS, a, i roto i nga whakaahua - .NET... Kaua e miharo: ko te mea i te wa e whakarite ana i te tuhinga, kaore he hapa i kitea i te whakamatautau i te tono tuatahi, engari ko ratou. i kitea i tetahi atu.

mutunga

Ka kite koe, kaore he mea uaua!

Ko te tikanga, mena kei a koe he kaikohi anga kua mahi, engari kaore koe e hiahia ki nga Kubernetes, ko te taapiri whakamatautau ki a ia he mahi ngawari ake i te korero i konei. Na roto GitLab CI tuhinga ka kitea e koe etahi tauira mo Ruby, Haere, Gradle, Maven me etahi atu.
