Hōʻike ka pou i nā hana e hoʻokaʻawale i ka hoʻokele o nā palapala SSL mai hoʻohana ʻana и AWS.
he mea hana e hiki ai iā mākou ke hoʻokō i kēia hiʻohiʻona. Hiki iā ia ke hana me nā palapala SSL mai Let's Encrypt, mālama iā lākou ma Amazon Certificate Manager, hoʻohana i ka Route53 API no ka hoʻokō ʻana i ka hoʻokūkū DNS-01, a ʻo ka hope, hoʻouna i nā leka hoʻomaopopo iā SNS. IN acme-dns-alanui53 Aia kekahi hana i kūkulu ʻia no ka hoʻohana ʻana i loko o AWS Lambda, a ʻo ia ka mea e pono ai mākou.
Ua māhele ʻia kēia ʻatikala i 4 mau ʻāpana:
- ka hana ʻana i kahi faila zip;
- hana i kahi hana IAM;
- e hana ana i kahi hana lambda e holo ana acme-dns-alanui53;
- ka hana ʻana i kahi manawa CloudWatch e hoʻoulu i kahi hana 2 mau manawa i ka lā;
'Ōlelo Aʻo: Ma mua o kou hoʻomaka ʻana pono ʻoe e hoʻokomo и
Ke hana ʻana i kahi faila zip
Ua kākau ʻia ʻo acme-dns-route53 ma GoLang a kākoʻo i ka mana ma lalo o 1.9.
Pono mākou e hana i kahi faila zip me kahi binary acme-dns-route53 i loko. No ka hana ʻana i kēia pono ʻoe e hoʻokomo acme-dns-route53 mai ka waihona waihona GitHub me ka hoʻohana ʻana i ke kauoha go install:
$ env GOOS=linux GOARCH=amd64 go install github.com/begmaroman/acme-dns-route53Hoʻokomo ʻia ka binary i loko $GOPATH/bin papa kuhikuhi. E ʻoluʻolu e hoʻomaopopo i ka wā o ka hoʻokomo ʻana ua kuhikuhi mākou i ʻelua mau wahi i hoʻololi ʻia: GOOS=linux и GOARCH=amd64. Hoʻomaopopo lākou i ka Go compiler pono e hana i kahi binary kūpono no ka Linux OS a me ka hoʻolālā amd64 - ʻo ia ka mea e holo nei ma AWS.
Manaʻo ʻo AWS e kau ʻia kā mākou papahana i kahi faila zip, no laila e hana mākou acme-dns-route53.zip waihona e loaʻa ai ka binary hou i hoʻokomo ʻia:
$ zip -j ~/acme-dns-route53.zip $GOPATH/bin/acme-dns-route53'Ōlelo Aʻo: Pono ka binary ma ke kumu o ka waihona zip. No kēia mea mākou e hoʻohana ai -j hae.
I kēia manawa ua mākaukau kā mākou inoa inoa zip no ka hoʻolaha ʻana, ʻo ka mea i koe wale nō ke hana i kahi kuleana me nā kuleana kūpono.
Ke hana nei i kahi hana IAM
Pono mākou e hoʻonohonoho i kahi kuleana IAM me nā kuleana i koi ʻia e kā mākou lambda i ka wā e hoʻokō ai.
E kāhea kākou i kēia kulekele lambda-acme-dns-route53-executor a hāʻawi koke iā ia i kahi kuleana kumu AWSLambdaBasicExecutionRole. E ʻae kēia i kā mākou lambda e holo a kākau i nā lāʻau i ka lawelawe AWS CloudWatch.
ʻO ka mea mua, hana mākou i kahi faila JSON e wehewehe ana i kā mākou kuleana. E ʻae kēia i nā lawelawe lambda e hoʻohana i ka hana lambda-acme-dns-route53-executor:
$ touch ~/lambda-acme-dns-route53-executor-policy.jsonʻO nā mea i loko o kā mākou faila penei:

ʻO ke kuleana o lambda-acme-dns-route53-executor hana ʻia, i kēia manawa pono mākou e kuhikuhi i nā ʻae no ia. ʻO ke ala maʻalahi e hana i kēia, ʻo ia ka hoʻohana ʻana i ke kauoha aws iam attach-role-policy, hoʻoholo i ke kulekele ARN AWSLambdaBasicExecutionRole penei:

Ke hana nei i kahi hana lambda e holo ana acme-dns-alanui53
Hooray! I kēia manawa hiki iā ʻoe ke kau i kā mākou hana i AWS me ka hoʻohana ʻana i ke kauoha aws lambda create-function. Pono e hoʻonohonoho ʻia ka lambda me ka hoʻohana ʻana i nā ʻano hoʻololi kaiapuni:

}Ke hana nei i kahi manawa CloudWatch e hoʻomaka i kahi hana 2 mau manawa i ka lā
ʻO ka hana hope e hoʻonohonoho i ka cron, e kāhea i kā mākou hana ʻelua i ka lā:
- hana i kahi lula CloudWatch me ka waiwai
schedule_expression. - e hana i kahi pahuhopu lula (he aha ka mea e hoʻokō ʻia) ma ke kuhikuhi ʻana i ka ARN o ka hana lambda.
- hāʻawi i ka ʻae i ka lula e kāhea i ka hana lambda.
Ma lalo iho ua hoʻopili wau i kaʻu Terraform config, akā ʻoiaʻiʻo ua hana ʻia kēia me ka hoʻohana ʻana i ka console AWS a i ʻole AWS CLI.
