Ukuzenzekela koMasibethele Ulawulo lwesatifikethi se-SSL sisebenzisa umngeni we-DNS-01 kunye ne-AWS

Isithuba sichaza amanyathelo okuzenzekelayo ulawulo lwezatifikethi ze-SSL ukusuka Masiguqulele i-CA usebenzisa DNS-01 umngeni ΠΈ AWS.

i-acme-dns-route53 sisixhobo esiza kusivumela ukuba siphumeze oluphawu. Inokusebenza kunye nezatifikethi ze-SSL ezivela kwi-Let Encrypt, zigcine kwi-Amazon Certificate Manager, sebenzisa i-Route53 API ukuphumeza umngeni we-DNS-01, kwaye, ekugqibeleni, izaziso zokutyhala kwi-SNS. IN i-acme-dns-route53 Kukho nokusebenza eyakhelwe-ngaphakathi ukuze isetyenziswe ngaphakathi kwe-AWS Lambda, kwaye yile nto siyifunayo.

Eli nqaku lahlulwe laba ngamacandelo ama-4:

  • yenza ifayile ye-zip;
  • ukudala indima ye-IAM;
  • ukwenza umsebenzi we-lambda osebenzayo i-acme-dns-route53;
  • ukudala isibali-xesha se-CloudWatch esidala umsebenzi amaxesha ama-2 ngosuku;

Phawula: Ngaphambi kokuba uqale kufuneka ufake IGoLang 1.9+ ΠΈ I-AWS CLI

Ukwenza ifayile ye-zip

i-acme-dns-route53 ibhalwe kwiGoLang kwaye ixhasa inguqulelo engekho ngaphantsi kwe-1.9.

Kufuneka senze ifayile ye-zip nge-binary acme-dns-route53 ngaphakathi. Ukwenza oku kufuneka ufake acme-dns-route53 ukusuka kwindawo yokugcina yeGitHub usebenzisa umyalelo go install:

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

Ibinary ifakiwe $GOPATH/bin ulawulo. Nceda uqaphele ukuba ngexesha lofakelo sichaze iimeko ezimbini ezitshintshileyo: GOOS=linux ΠΈ GOARCH=amd64. Bayenza icace kwi-Go compiler ukuba idinga ukwenza ibhinary efanelekileyo yeLinux OS kunye ne-amd64 yoyilo-le yiloo nto esebenza kwi-AWS.
I-AWS ilindele ukuba inkqubo yethu ifakwe kwifayile ye-zip, ngoko makhe siyile acme-dns-route53.zip ugcino oluza kuqulatha ibhinary esanda kufakwa:

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

Phawula: Ibinary kufuneka ibe kwingcambu yendawo yokugcina ye-zip. Kule nto sisebenzisayo -j iflegi.

Ngoku igama lethu lesidlaliso le-zip lilungele ukuthunyelwa, konke okuseleyo kukudala indima ngamalungelo ayimfuneko.

Ukudala indima ye-IAM

Kufuneka siseke indima ye-IAM ngamalungelo afunwa yi-lambda yethu ngexesha lokuphunyezwa kwayo.
Masiyibize le polisi lambda-acme-dns-route53-executor kwaye ngoko nangoko umnike indima esisiseko AWSLambdaBasicExecutionRole. Oku kuya kuvumela i-lambda yethu ukuba iqhube kwaye ibhale iilogi kwinkonzo ye-AWS CloudWatch.
Okokuqala, senza ifayile ye-JSON echaza amalungelo ethu. Oku kuya kuvumela iinkonzo ze-lambda ukuba zisebenzise indima lambda-acme-dns-route53-executor:

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

Imixholo yefayile yethu ngolu hlobo lulandelayo:

{
    "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/*"
            ]
        }
    ]
}

Ngoku masiqhube umyalelo aws iam create-role ukwenza indima:

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

Phawula: khumbula umgaqo-nkqubo we-ARN (i-Amazon Resource Name) - siya kuyidinga kumanyathelo alandelayo.

Indima lambda-acme-dns-route53-executor yenziwe, ngoku kufuneka sikhankanye iimvume zayo. Eyona ndlela ilula yokwenza oku kukusebenzisa umyalelo aws iam attach-role-policy, ukupasa umgaqo-nkqubo ARN AWSLambdaBasicExecutionRole ngolu hlobo:

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

Phawula: uluhlu oluneminye imigaqo-nkqubo inokufumaneka apha.

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

Uxolo! Ngoku ungathumela umsebenzi wethu kwi-AWS usebenzisa umyalelo aws lambda create-function. I-lambda kufuneka iqwalaselwe kusetyenziswa oku kuguquguquka kwemekobume kulandelayo:

  • AWS_LAMBDA - yenza kucace i-acme-dns-route53 ukuba ukuphunyezwa kwenzeka ngaphakathi AWS Lambda.
  • DOMAINS - Uluhlu lwemimandla eyahlulwe ngeekoma.
  • LETSENCRYPT_EMAIL - iqulathe Masiguqulele i-imeyile ngokuntsonkotha.
  • NOTIFICATION_TOPIC β€” igama leSihloko seSaziso se-SNS (ukhetho).
  • STAGING - ngexabiso 1 indawo yeqonga isetyenziswa.
  • 1024 MB - umda wememori, unokutshintshwa.
  • 900 imizuzwana (imizuzu eyi-15) - ixesha liphelile.
  • acme-dns-route53 - igama le-binary yethu, ekwi-archive.
  • fileb://~/acme-dns-route53.zip β€” indlela eya kwindawo yogcino-mpepha esiyidalileyo.

Ngoku masibeke:

$ 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

Ukudala i-CloudWatch timer eyenza umsebenzi ngamaxesha e-2 ngosuku

Inyathelo lokugqibela kukuseta icron, ebiza umsebenzi wethu kabini ngemini:

  • yenza umthetho we-CloudWatch ngexabiso schedule_expression.
  • yenza umgaqo ekujoliswe kuwo (yintoni emayiphunyezwe) ngokukhankanya i ARN yomsebenzi we lambda.
  • nika imvume kumgaqo ukubiza umsebenzi we-lambda.

Apha ngezantsi ndincamathele uqwalaselo lwam lweTerraform, kodwa eneneni oku kwenziwa ngokulula kakhulu usebenzisa i-AWS console okanye 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}"
}

Ngoku uqwalaselwe ukuba wenze ngokuzenzekelayo kwaye uhlaziye izatifikethi ze-SSL
