Ukuzenzakalela kokuphathwa kwesitifiketi se-SSL kusetshenziswa inselele ye-DNS-01 kanye ne-AWS

Okuthunyelwe kuchaza izinyathelo zokwenza ngokuzenzakalelayo ukuphathwa kwezitifiketi ze-SSL kusuka Masibethele i-CA usebenzisa Inselele ye-DNS-01 ΠΈ AWS.

i-acme-dns-route53 iyithuluzi elizosivumela ukuthi senze lesi sici. Ingasebenza nezitifiketi ze-SSL ezivela ku-Let's Encrypt, izigcine ku-Amazon Certificate Manager, isebenzise i-Route53 API ukuze iqalise inselele ye-DNS-01, futhi, ekugcineni, iphushele izaziso ku-SNS. IN i-acme-dns-route53 Kukhona nokusebenza okwakhelwe ngaphakathi ukuze kusetshenziswe ngaphakathi kwe-AWS Lambda, futhi yilokhu esikudingayo.

Lesi sihloko sihlukaniswe izigaba ezi-4:

  • ukudala ifayela le-zip;
  • ukwakha indima ye-IAM;
  • ukudala umsebenzi we-lambda osebenzayo i-acme-dns-route53;
  • ukudala isibali sikhathi se-CloudWatch esicupha umsebenzi izikhathi ezi-2 ngosuku;

Qaphela: Ngaphambi kokuthi uqale udinga ukufaka I-GoLang 1.9+ ΠΈ I-AWS CLI

Idala ifayela le-zip

I-acme-dns-route53 ibhalwe ku-GoLang futhi isekela inguqulo engekho ngaphansi kuka-1.9.

Sidinga ukudala ifayela le-zip elinambambili acme-dns-route53 ngaphakathi. Ukuze wenze lokhu udinga ukufaka acme-dns-route53 kusuka endaweni yokugcina ye-GitHub usebenzisa umyalo go install:

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

I-binary ifakiwe $GOPATH/bin umkhombandlela. Sicela uqaphele ukuthi ngesikhathi sokufakwa sicacise izindawo ezimbili ezishintshile: GOOS=linux ΠΈ GOARCH=amd64. Bakwenza kucace ku-Go compiler ukuthi idinga ukudala kanambambili ofanele i-Linux OS kanye ne-amd64 architecture - yilokhu okusebenza ku-AWS.
I-AWS ilindele ukuthi uhlelo lwethu lusetshenziswe kufayela le-zip, ngakho-ke masidale acme-dns-route53.zip ingobo yomlando ezoqukatha kanambambili esanda kufakwa:

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

Qaphela: Okunambambili kufanele kube kuyimpande yengobo yomlando ye-zip. Kulokhu sisebenzisa -j ifulege.

Manje isiteketiso sethu se-zip sesilungele ukusetshenziswa, okusele nje ukudala indima ngamalungelo adingekayo.

Ukudala indima ye-IAM

Sidinga ukumisa indima ye-IAM ngamalungelo adingwa i-lambda yethu ngesikhathi isenziwa.
Asibize le nqubomgomo lambda-acme-dns-route53-executor futhi ngokushesha umnikeze indima eyisisekelo AWSLambdaBasicExecutionRole. Lokhu kuzovumela i-lambda yethu ukuthi isebenze futhi ibhale amalogi kusevisi ye-AWS CloudWatch.
Okokuqala, sakha ifayela le-JSON elichaza amalungelo ethu. Lokhu kuzovumela izinsiza ze-lambda ukuthi zisebenzise indima lambda-acme-dns-route53-executor:

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

Okuqukethwe kwefayela lethu kungokulandelayo:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "logs:CreateLogGroup"
            ],
            "Resource": "arn:aws:logs:<AWS_REGION>:<AWS_ACCOUNT_ID>:*"
        },
        {
            "Effect": "Allow",
            "Action": [
                "logs:PutLogEvents",
                "logs:CreateLogStream"
            ],
            "Resource": "arn:aws:logs:<AWS_REGION>:<AWS_ACCOUNT_ID>:log-group:/aws/lambda/acme-dns-route53:*"
        },
        {
            "Sid": "",
            "Effect": "Allow",
            "Action": [
                "route53:ListHostedZones",
                "cloudwatch:PutMetricData",
                "acm:ImportCertificate",
                "acm:ListCertificates"
            ],
            "Resource": "*"
        },
        {
            "Sid": "",
            "Effect": "Allow",
            "Action": [
                "sns:Publish",
                "route53:GetChange",
                "route53:ChangeResourceRecordSets",
                "acm:ImportCertificate",
                "acm:DescribeCertificate"
            ],
            "Resource": [
                "arn:aws:sns:${var.region}:<AWS_ACCOUNT_ID>:<TOPIC_NAME>",
                "arn:aws:route53:::hostedzone/*",
                "arn:aws:route53:::change/*",
                "arn:aws:acm:<AWS_REGION>:<AWS_ACCOUNT_ID>:certificate/*"
            ]
        }
    ]
}

Manje ake siqhube umyalo aws iam create-role ukudala indima:

$ aws iam create-role --role-name lambda-acme-dns-route53-executor 
 --assume-role-policy-document ~/lambda-acme-dns-route53-executor-policy.json

Qaphela: khumbula inqubomgomo i-ARN (Igama Lensiza Ye-Amazon) - sizoyidinga ezinyathelweni ezilandelayo.

Indima lambda-acme-dns-route53-executor idaliwe, manje sidinga ukucacisa izimvume zayo. Indlela elula yokwenza lokhu ukusebenzisa umyalo aws iam attach-role-policy, inqubomgomo yokuphasisa i-ARN AWSLambdaBasicExecutionRole kanje:

$ aws iam attach-role-policy --role-name lambda-acme-dns-route53-executor 
--policy-arn arn:aws:iam::aws:policy/service-role/AWSLambdaBasicExecutionRole

Qaphela: uhlu olunezinye izinqubomgomo lungatholakala lapha.

Idala umsebenzi we-lambda osebenzayo i-acme-dns-route53

Hooray! Manje usungakwazi ukuthumela umsebenzi wethu ku-AWS usebenzisa umyalo aws lambda create-function. I-lambda kufanele imiswe kusetshenziswa okuguquguqukayo kwemvelo okulandelayo:

  • AWS_LAMBDA - ikwenza kucace i-acme-dns-route53 lokho kubulawa kwenzeka ngaphakathi kwe-AWS Lambda.
  • DOMAINS β€” uhlu lwezizinda ezihlukaniswe ngokhefana.
  • LETSENCRYPT_EMAIL - iqukethe Masibethele I-imeyili.
  • NOTIFICATION_TOPIC - Igama le-SNS Notification Topic (uyazikhethela).
  • STAGING - ngenani 1 indawo yesiteji isetshenziswa.
  • 1024 MB - umkhawulo wememori, ungashintshwa.
  • 900 amasekhondi (15 min) - ukuphela kwesikhathi.
  • acme-dns-route53 - Igama le-binary yethu, elisendaweni yomlando.
  • fileb://~/acme-dns-route53.zip - indlela eya endaweni yomlando esiyidalile.

Manje masisebenzise:

$ aws lambda create-function 
 --function-name acme-dns-route53 
 --runtime go1.x 
 --role arn:aws:iam::<AWS_ACCOUNT_ID>:role/lambda-acme-dns-route53-executor 
 --environment Variables="{AWS_LAMBDA=1,DOMAINS="example1.com,example2.com",[email protected],STAGING=0,NOTIFICATION_TOPIC=acme-dns-route53-obtained}" 
 --memory-size 1024 
 --timeout 900 
 --handler acme-dns-route53 
 --zip-file fileb://~/acme-dns-route53.zip

 }

Idala isibali sikhathi se-CloudWatch esicupha umsebenzi izikhathi ezi-2 ngosuku

Isinyathelo sokugcina ukusetha i-cron, ebiza umsebenzi wethu kabili ngosuku:

  • dala umthetho we-CloudWatch ngevelu schedule_expression.
  • dala umgomo womthetho (lokho okufanele kwenziwe) ngokucacisa i-ARN yomsebenzi we-lambda.
  • nikeza imvume kumthetho wokushayela umsebenzi we-lambda.

Ngezansi nginamathisele ukucushwa kwami ​​kwe-Terraform, kodwa empeleni lokhu kwenziwa kalula kusetshenziswa ikhonsoli ye-AWS noma i-AWS CLI.

# Cloudwatch event rule that runs acme-dns-route53 lambda every 12 hours
resource "aws_cloudwatch_event_rule" "acme_dns_route53_sheduler" {
  name                = "acme-dns-route53-issuer-scheduler"
  schedule_expression = "cron(0 */12 * * ? *)"
}

# Specify the lambda function to run
resource "aws_cloudwatch_event_target" "acme_dns_route53_sheduler_target" {
  rule = "${aws_cloudwatch_event_rule.acme_dns_route53_sheduler.name}"
  arn  = "${aws_lambda_function.acme_dns_route53.arn}"
}

# Give CloudWatch permission to invoke the function
resource "aws_lambda_permission" "permission" {
  action        = "lambda:InvokeFunction"
  function_name = "${aws_lambda_function.acme_dns_route53.function_name}"
  principal     = "events.amazonaws.com"
  source_arn    = "${aws_cloudwatch_event_rule.acme_dns_route53_sheduler.arn}"
}

Manje usulungiselelwe ukuthi udale futhi ubuyekeze ngokuzenzakalelayo izitifiketi ze-SSL
