Elastic Beanstalk environment forces update on each apply #1471

Open stuffandthings opened 7 years ago

stuffandthings commented 7 years ago

Hello,

Every time I run terraform apply my elastic beanstalk environment is marked for update, which in turn re-creates my environment. This is clearly undesirable behavior.

Terraform Version

Terraform v0.10.2

Affected Resource(s)

Terraform Configuration Files

resource "aws_elastic_beanstalk_environment" "backend" {
  name                = "backend-${var.environment}"
  application         = "backend"
  solution_stack_name = "64bit Amazon Linux 2017.03 v2.4.3 running PHP 5.6"
  tier                = "WebServer"

  setting {
  ...
  }
}

Expected Behavior

No change should be detected

Actual Behavior

Terraform thinks I've made a change

Steps to Reproduce

  1. Run terraform apply
  2. Run terraform apply again with no changes
stuffandthings commented 7 years ago

I narrowed it down to an issue with these two setting options. My current workaround is to just comment them out:

  setting {
    namespace = "aws:elasticbeanstalk:application"
    name      = "Application Healthcheck URL"
    value     = "HTTP:80/elb-status"
  }
  setting {
    namespace = "aws:autoscaling:launchconfiguration"
    name      = "SSHSourceRestriction"
    value     = "tcp, 22, 22, ${var.bastion_security_group}"
  }
stuffandthings commented 7 years ago

One of the side effects of this ends up being a security critical issue. Not being able to configure SSHSourceRestriction to avoid the constant refreshes by default will keep port 22 open to the world.

mbklein commented 6 years ago

I'm having this issue as well. I can't not use the Application Healthcheck URL without compromising my deployment, so I'm stuck letting it update every environment on each apply.

DanielSchaffer commented 6 years ago

This also happens with the aws:autoscaling:launchconfiguration IamInstanceProfile setting. Looks like the setting ID changes every time.

ppemmaraju-ellevest commented 6 years ago

Terraform v0.11.7

But running into issues with: setting { name = "SSLReferencePolicy" namespace = "aws:elb:policies:TLSHighPolicy" value = "ELBSecurityPolicy-TLS-1-2-2017-01" }

hshafy commented 6 years ago

I'm also facing the same issue, any update or work around?

arturstorm commented 6 years ago

It's annoying to wait 10 min for beanstalk update even there no changes

chucknelson commented 6 years ago

+1 - Also facing this issue which causes unnecessary deployment time.

mattboston commented 6 years ago

+1 I'm having this issue as well

<> terraform version Terraform v0.11.8

sertaco commented 6 years ago

Any update on this? Having the same issue when using aws:autoscaling:launchconfiguration IamInstanceProfile setting. I have to give an instance profile. Is there any workaround to suppress updates?

RobertPaulson90 commented 6 years ago

Same problems... Really a PITA

mbklein commented 6 years ago

@mitchellh Any chance of getting some official word on this? It's a pretty big usability issue.

caJaeger commented 5 years ago

I have to agree that this is pretty serious, it's completely crippling my IaC, not only does this apply every time for no reason, it also prevents other resources from being updated because it fails to update constantly with:

aws_elastic_beanstalk_environment.default: Error waiting for Elastic Beanstalk Environment (e-nwn8rhh3xs) to become ready: 2 errors occurred:
    * 2019-02-27 19:33:27.54 +0000 UTC (e-nwn8rhh3xs) : Service:AmazonCloudFormation, Message:No updates are to be performed.
    * 2019-02-27 19:33:28.574 +0000 UTC (e-nwn8rhh3xs) : Environment tag update failed.

This is pretty much unusable for my purposes.

GarlicDipping commented 5 years ago

Any updates??? Seems like IamInstanceProfile and SecurityGroups settings force this change...

*Edit So, after searching a bit, I found out that

  1. For IamInstanceProfile setting, Use name instead of id. Using id field will make terraform think your beanstalk environment changed.
  2. Don't use 'awseb' name prefix with security group. AWS Provider will ignore if security group's name starts with it. Here is the code reference.
rpadovani commented 5 years ago

Another important point for the SSHSourceRestriction setting: do NOT put spaces after commas.

This will trigger an update, so do not use it:

  setting {
    namespace = "aws:autoscaling:launchconfiguration"
    name      = "SSHSourceRestriction"
    value     = "tcp, 22, 22, ${var.bastion_security_group}"
  }

while this WILL NOT:

  setting {
    namespace = "aws:autoscaling:launchconfiguration"
    name      = "SSHSourceRestriction"
    value     = "tcp,22,22,${var.bastion_security_group}"
  }
andrewjeffree commented 5 years ago

So I found a bug in the beanstalk API almost a year ago that essentially meant they were returning null values in certain situations with SSHSourceRestriction. They emailed me this morning say it should be fixed now, perhaps it'll solve this problem.

krunalsabnis commented 5 years ago

I have this issues with many other elements. see below (- & +) removing and adding. Terraform v0.12.3

rpadovani commented 5 years ago 
* /+ setting {
  + name      = "Subnets"
  + namespace = "aws:ec2:vpc"
  + value     = "subnet-0533bc84xxxxx, subnet-0849547f75xxxx"
  }
  - setting {
  - name      = "Subnets" -> null
  - namespace = "aws:ec2:vpc" -> null
  - value     = "subnet-0533bc84xxxxx,subnet-0849547f75xxxx" -> null
  }

@krunalsabnis this is because you have a space between the first and the second subnet, after the comma. Try removing the space in the value, and it should stop this behavior

jborrey commented 5 years ago

I observed ultra strange behavior - the post by @GarlicDipping prompted me to try this, so thanks!

My EB deployment had a bunch of custom settings, and each Terraform apply would re-apply these settings as a no-op. These were settings like subnets, sgs, load balancer settings, service role, instance profile, etc.

I changed only the IamInstanceProfile from a full ARN to just the name, and instantly the entire problem went away for all settings.

Previous: arn:aws:iam::xxx:instance-profile/eb-ec2-role After: eb-ec2-role

Update: In a different EB app, this trick didn't resolve the problem.

Rmannn commented 5 years ago

Adding resource = "" to setting section fixes my issue.

mmulligan03 commented 5 years ago

Similar to @krunalsabnis I get this for every setting when applying terraform to Beanstalk environment Using terraform v 0.12.6.

mleonhard commented 5 years ago

Bug is present in provider "aws" { version = "~> 2.30" } released 2019-09-26.

Two changes work around it for me:

  1. Add resource="" to each setting section. (Thanks @Rmannn ! 👍)
  2. Stop including settings which Elastic Beanstalk will ignore and not return in queries.

Working version: 

resource "aws_elastic_beanstalk_environment" "api_service" {
  name = "${var.instance_name}-api-service"
  application = aws_elastic_beanstalk_application.api_service.name
  cname_prefix = "com-company-${var.instance_name}-api"

  # Prod & Staging get expensive Load Balancers.  Other deployments get cheap Elastic IPs.
  setting {
    namespace = "aws:elasticbeanstalk:environment"
    name = "EnvironmentType"
    value = var.is_prod_or_staging ? "LoadBalanced" : "SingleInstance"
    // These empty 'resource' values prevent updating the environment on every apply.
    // See https://github.com/terraform-providers/terraform-provider-aws/issues/1471#issuecomment-522977469
    resource = ""
  }

  // Include the 'LoadBalancerType' setting only in Prod/Staging deployments.
  // The Beanstalk API ignores the LoadBalancerType setting when EnvironmentType=SingleInstance.
  // When Terraform queries the application's settings, the Beanstalk API does not return the
  // LoadBalancerType entry, so Terraform tries to add it.  This makes Terraform update the
  // application on *every* apply.
  // See https://github.com/terraform-providers/terraform-provider-aws/issues/1471#issuecomment-522977469
  // This 'dynamic' ugly hack is required because Terraform has no conditionals.

  }

UdhavPawar commented 4 years ago

Faced exact same issue. What solved the issue for me (these are not my solutions, found them from reading this and other posts):

  1. Add resource = "" in every environment setting
  2. Remove space between subnets that you are passing to the VPC setting of environment
  3. Remove the environment setting for BeanStalk to send default GET requests to custom healthcheck path, instead update load-balancer healthcheck path with custom path
  4. update the gateway_id to nat_gateway_id if you are attaching NAT GW to a private subnet's route table

Hope these help :)

ghost commented 4 years ago

Same issue here when trying to use aws:elb:policies:backendkey PublicKey, Terraform force the update with exactly the same certificate PEM content.

  setting {
    namespace = "aws:elb:policies:backendencryption"
    name      = "PublicKeyPolicyNames"
    value     = "backendkey"
    resource  = ""
  }

  setting {
    namespace = "aws:elb:policies:backendencryption"
    name      = "InstancePorts"
    value     = "443"
    resource  = ""
  }

  setting {
    namespace = "aws:elb:policies:backendkey"
    name      = "PublicKey"
    value     = tls_self_signed_cert.backend.cert_pem
    resource  = ""
  }

EDIT: To fix this issue, the public key must be passed instead of the certificate and it must be formatted to contain only the raw key:

  setting {
    namespace = "aws:elb:policies:backendencryption"
    name      = "PublicKeyPolicyNames"
    value     = "backendkey"
    resource  = ""
  }

  setting {
    namespace = "aws:elb:policies:backendencryption"
    name      = "InstancePorts"
    value     = "443"
    resource  = ""
  }

  setting {
    namespace = "aws:elb:policies:backendkey"
    name      = "PublicKey"
    value     = replace(replace(tls_private_key.backend.public_key_pem, "/-----[A-Z ]+-----/", ""), "/\\s/", "")
    resource  = ""
  }
montross50 commented 4 years ago

As others have mentioned, you need to watch out for spaces in your subnets. In addition the subnets appear to be sorted alphabetically. 

setting {
    namespace = "aws:ec2:vpc"
    name      = "Subnets"
    value     = join(",", sort(var.private_subnets))
    resource  = ""
  }

where var.private_subnets is a list(string) of subnets fixed my issue.

DanielSchaffer commented 4 years ago

One other thing I just noticed was that when you have lists of things (subnets, security groups), sometimes they come back in a different order than your TF config specifies, so it detects a diff every time. Reorder the entries in the value to match what's coming back, and it should be set. That, plus the resource = "" hack is what fixed it all for me.

DarkBitz commented 3 years ago

I have the same problem but only for "ServiceRole" an empty resource property does not help.

setting {
    name = "ServiceRole"
    namespace = "aws:elasticbeanstalk:environment"
    value = aws_iam_role.eb_service_role.arn
    resource = ""
  }

Same as @nueces, I also tried manually configure ConfigDocument and that didn't work as well.

Actually I solved the problem - we need to sort the JSON content exactly like how the provider expects, otherwise it would think they're different.

eballetbaz commented 3 years ago

Hi @zen0wu, what do you mean by "sort the JSON content exactly like how the provider expect" ? Could you share a sample please ?

Thanks

nueces commented 3 years ago

@eballetbaz in my case instead of using jsonencode, I crafted the json as

value = "{\"Version\":1,\"Rules\":{\"Environment\":{\"ELB\":{\"ELBRequests4xx\":{\"Enabled\":false}}},\"Application\":{\"ApplicationRequests4xx\":{\"Enabled\":true}}}}}}"

To found the correct format I used the json output and then compare the old value for the field. Using this commands: 

terraform plan -out plan.out 
terraform show -json plan.out | jq > plan.json
SamuelNorbury commented 2 years ago

I thought it might be due to a string interpolated value with a space after comma, e.g.:

  setting {
    namespace = "aws:autoscaling:launchconfiguration"
    name      = "SecurityGroups"
    value = "${data.aws_security_group.somegroup.id}, ${data.aws_security_group.someothergroup.id}"
#--------------------------------------------------- ^ this space
  }

Which elasticbeanstalk would adjust every time:

      - setting {
          - name      = "SecurityGroups" -> null
          - namespace = "aws:autoscaling:launchconfiguration" -> null
          - value     = "sg-abc, sg-def -> null
        }
      + setting {
          + name      = "SecurityGroups"
          + namespace = "aws:autoscaling:launchconfiguration"
          + value     = "sg-abc,sg-def"
        }

Removing the space from the string value did not solve this happening every time though

Still experience this with terraform 0.14.10 and the aws provider 3.22.0 and the resource = "" in the setting.

  # module.eb-name.aws_elastic_beanstalk_environment.default will be updated in-place
  ~ resource "aws_elastic_beanstalk_environment" "default" {
        id                     = "e-xxxxxxxxxx"
        name                   = "eb-name"
        tags                   = {}
        # (15 unchanged attributes hidden)

      + setting {
          + name      = "ConfigDocument"
          + namespace = "aws:elasticbeanstalk:healthreporting:system"
          + value     = jsonencode(
                {
                  + Rules   = {
                      + Environment = {
                          + Application = {
                              + ApplicationRequests4xx = {
                                  + Enabled = false
                                }
                            }
                          + ELB         = {
                              + ELBRequests4xx = {
                                  + Enabled = true

                        }
                    }
                  + Version = 1
                }
            )
        }
      - setting {
          - name      = "ConfigDocument" -> null
          - namespace = "aws:elasticbeanstalk:healthreporting:system" -> null
          - value     = jsonencode(
                {
                  - Rules   = {
                      - Environment = {
                          - Application = {
                              - ApplicationRequests4xx = {
                                  - Enabled = false
                                }
                            }
                          - ELB         = {
                              - ELBRequests4xx = {
                                  - Enabled = true
                                }
                            }
                        }
                    }
                  - Version = 1
                }
            ) -> null
        }

I think this happens because jsonencode() orders the document and EB is expecting it in a specific order

echoboomer commented 2 years ago

This is still an issue in 3.74.0. How has this not been resolved? This is an absolute show stopper when it comes to creating or managing Elastic Beanstalk applications in Terraform - especially if you're importing an existing one. This creates a giant blindspot in an organization's ability to guarantee that infrastructure can be reliably managed using one tool.

azban commented 2 years ago

seems like the workaround from https://github.com/hashicorp/terraform-provider-aws/issues/1471#issuecomment-522977469 works for almost all cases.

echoboomer commented 2 years ago

It does not work in my case whatsoever.

azban commented 2 years ago

does it work after the first apply? have been using it for a few months and not had any of the same issues. there seem to be some underlying implicit configuration setting that happens that will update the state transparently on future plans, but plans have no updates.

Great question. I have an app that was created from the start using Terraform that I'll add resource = "" to each setting and see if that helps. In this case, I'm dealing with an imported environment. It seems risky to do an apply without knowing what it will actually alter, but there may be no choice.

azban commented 2 years ago

yea, not sure there is a good way to automate that process, but there's only so many settings to go through, so it may be bearable for manual review if you only have a few environments. :shrug:

SamuelNorbury commented 2 years ago

A workaround that seems to have worked for my team is adding resource = "" to every setting, as well as sorting any interpolated strings, like: 

  setting {
    namespace = "aws:autoscaling:asg"
    name      = "Availability Zones"
    value     = "Any"
    resource  = ""                                           # Add an empty resource
  }
  setting {
    namespace = "aws:autoscaling:launchconfiguration"
    name      = "SecurityGroups"
    value     = join(",", sort([data.aws_security_group.this.id, data.aws_security_group.that.id]))     # Use join() and sort()
    resource  = ""
  }

@g4rb1 correct me if I'm wrong.

snipergotya commented 2 years ago 
setting {
    name      = "SSHSourceRestriction"
    namespace = "aws:autoscaling:launchconfiguration"
    value     = "tcp,22,22,192.0.0.34/32"
    resource = ""
  }

Every time I use this option it causes my beanstalk to require an update. if i comment it out it works fine.

I'd like to make sure its included, any way to resolve this?

Also I'm not specifying the keypair setting, i'm wondering does it need to be used in conjunction with the keypair setting to work?

epomatti commented 2 years ago

Adding resource = "" solved it. Both tf and provider are the latest versions.

Any idea how to fix DBSubnets ?

        id                     = "e-zfvjkxrhap"
        name                   = "api-prod"
        tags                   = {}
        # (17 unchanged attributes hidden)

      + setting {
          + name      = "DBSubnets"
          + namespace = "aws:ec2:vpc"
          + value     = "subnet-071aa19a12d37195e,subnet-083bb9cec8b75cfcc"
        }
        # (27 unchanged blocks hidden)
    }
snipergotya commented 1 year ago

depending on how you are supplying the subnets you might need to sort them. sorting them fixed my issue with subnets changing.

EG: sort(["subnet-1", "subnet-2"])

khavishbhundoo commented 1 year ago

@snipergotya I am already sorting the subnets

  setting {
    namespace = "aws:ec2:vpc"
    name      = "DBSubnets"
    value     = join(",", sort(module.vpc.private_subnets))
    resource  = ""
  }
nueces commented 1 year ago

@khavishbhundoo try then to do a reverse before the join. You need to preset the string as terraform expect. You can check try to inspecting the output in json format to get more clues 

terraform plan -out plan.out 
terraform show -json plan.out  > plan.json

All i can see is the setting with the proper subnet in the json

              "resource": "",

But what about the previous value that was stored? can you found it and paste it here?

There is no value for DBSubnets for elastic beanstalk in resource_changes in before section but i see DBSubnets in after section

{
              "name": "DBSubnets",
