Automation ti Jẹ ki ká Encrypt SSL ijẹrisi isakoso lilo DNS-01 ipenija ati AWS

Ifiweranṣẹ naa ṣe apejuwe awọn igbesẹ lati ṣe adaṣe adaṣe iṣakoso ti awọn iwe-ẹri SSL lati Jẹ ki a Encrypt CA lilo DNS-01 ipenija и Aws.

acme-dns-route53 jẹ ọpa ti yoo gba wa laaye lati ṣe ẹya ara ẹrọ yii. O le ṣiṣẹ pẹlu awọn iwe-ẹri SSL lati Jẹ ki Encrypt, fi wọn pamọ sinu Oluṣakoso Ijẹrisi Amazon, lo Route53 API lati ṣe imuse ipenija DNS-01, ati, nikẹhin, Titari awọn iwifunni si SNS. IN acme-dns-route53 Iṣẹ ṣiṣe tun wa fun lilo inu AWS Lambda, ati pe eyi ni ohun ti a nilo.

A pin nkan yii si awọn apakan mẹrin:

• ṣiṣẹda zip faili;
• ṣiṣẹda ipa IAM;
• ṣiṣẹda iṣẹ lambda ti o nṣiṣẹ acme-dns-route53;
• ṣiṣẹda aago CloudWatch ti o nfa iṣẹ kan ni igba 2 ni ọjọ kan;

akiyesi: Ṣaaju ki o to bẹrẹ o nilo lati fi sori ẹrọ GoLang 1.9+ и Aws CLI

Ṣiṣẹda faili zip kan

acme-dns-route53 jẹ kikọ ni GoLang ati pe o ṣe atilẹyin ẹya ko kere ju 1.9.

A nilo lati ṣẹda faili zip pẹlu alakomeji acme-dns-route53 inu. Lati ṣe eyi o nilo lati fi sori ẹrọ acme-dns-route53 lati ibi ipamọ GitHub nipa lilo aṣẹ naa go install:

$ env GOOS=linux GOARCH=amd64 go install github.com/begmaroman/acme-dns-route53

Alakomeji ti fi sori ẹrọ ni $GOPATH/bin liana. Jọwọ ṣe akiyesi pe lakoko fifi sori ẹrọ a ṣalaye awọn agbegbe meji ti o yipada: GOOS=linux и GOARCH=amd64. Wọn jẹ ki o yege si Go alakojo pe o nilo lati ṣẹda alakomeji o dara fun Linux OS ati amd64 faaji - eyi ni ohun ti nṣiṣẹ lori AWS.
AWS nireti pe ki a gbe eto wa sinu faili zip kan, nitorinaa jẹ ki a ṣẹda acme-dns-route53.zip ile-ipamọ eyiti yoo ni alakomeji ti a fi sori ẹrọ tuntun ninu:

$ zip -j ~/acme-dns-route53.zip $GOPATH/bin/acme-dns-route53

akiyesi: Alakomeji yẹ ki o wa ni gbongbo ti ibi ipamọ zip. Fun eyi a lo -j asia.

Bayi orukọ apeso zip wa ti ṣetan fun imuṣiṣẹ, gbogbo ohun ti o ku ni lati ṣẹda ipa kan pẹlu awọn ẹtọ to ṣe pataki.

Ṣiṣẹda ipa IAM kan

A nilo lati ṣeto ipa IAM kan pẹlu awọn ẹtọ ti o nilo nipasẹ lambda wa lakoko ipaniyan rẹ.
Jẹ ki a pe eto imulo yii lambda-acme-dns-route53-executor ati lẹsẹkẹsẹ fun u ni ipa ipilẹ AWSLambdaBasicExecutionRole. Eyi yoo gba lambda wa laaye lati ṣiṣẹ ati kọ awọn akọọlẹ si iṣẹ AWS CloudWatch.
Ni akọkọ, a ṣẹda faili JSON kan ti o ṣapejuwe awọn ẹtọ wa. Eyi yoo gba awọn iṣẹ lambda laaye lati lo ipa naa lambda-acme-dns-route53-executor:

$ touch ~/lambda-acme-dns-route53-executor-policy.json

Awọn akoonu ti faili wa jẹ bi atẹle:
