I am looking to limit the size of the client body based on the content type in nginx.

location / {
    if ($content_type = "application/json") {
            client_max_body_size 1M;
            client_body_buffer_size 512K;
    }
    ...
    ...
}

I've tried the above if condition which fails with below error.

nginx: [emerg] "client_max_body_size" directive is not allowed here

I have also tried using this without any effect

location ~* ^.+\.json {
   client_max_body_size 1M;
   client_body_buffer_size 512K;
}

I am trying to configure two-way SSL with SSL certs (for server and client) signed by Intermediate CAs. This is what I have done so far following this tutorial.

Server - nginx application

Nginx is configured with SSL certificate (signed by an Intermediate CA).

server {
  listen 443;
  server_name app-ca.test.com;
  ssl on;

  ssl_certificate /root/ca/intermediate/certs/app-plus-intermediate.pem;
  ssl_certificate_key /root/ca/intermediate/private/app-ca-interm-ca.test.com.key.pem;
  ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
  ssl_ciphers  HIGH:!aNULL:!MD5;
  ssl_prefer_server_ciphers   on;

  # I have also tried adding the Intermediate CA cert in vain
  # ssl_client_certificate /root/client_rootca_intermediate.crt;
  ssl_client_certificate /root/client_rootca.crt;
  ssl_verify_client on;

  location / {
      root /usr/share/nginx/massl;
      index index.html index.htm;
  }
}

Client - curl or OpenSSL s_client

I have a client certificate signed by some other Intermediate CA, which fails with 400 The SSL certificate error

I have also tried to pass (-cert option in openssl command) Client's Intermediate CA and Root CA along with the client certificate in vain.

$ cat /root/ca/intermediate/certs/client.cert.pem /root/ca/intermediate/certs/intermediate.cert.pem > /root/ca/intermediate/certs/client_plus_intermediate.cert.pem

$ cat /root/ca/intermediate/certs/client.cert.pem /root/ca/intermediate/certs/intermediate.cert.pem > /root/ca/intermediate/certs/intermediate_plus_client.cert.pem

$ cat /root/ca/intermediate/certs/client.cert.pem /root/ca/intermediate/certs/intermediate.cert.pem /root/ca/certs/ca.cert.pem > /root/ca/intermediate/certs/client_plus_intermediate_plus_ca.cert.pem

I have shortened the longs hashes for brevity.

Interestingly, the above command works fine if I use certificates of Client's Root CA or Client's Intermediate CA.

I am trying to use a nested loop in terraform. I have two list variables list_of_allowed_accounts and list_of_images, and looking to iterate over list list_of_images and then iterate over list list_of_allowed_accounts.

Here is my terraform code.

variable "list_of_allowed_accounts" {
  type    = "list"
  default = ["111111111", "2222222"]
}

variable "list_of_images" {
  type    = "list"
  default = ["alpine", "java", "jenkins"]
}

data "template_file" "ecr_policy_allowed_accounts" {
  template = "${file("${path.module}/ecr_policy.tpl")}"

  vars {
    count = "${length(var.list_of_allowed_accounts)}"
    account_id = "${element(var.list_of_allowed_accounts, count.index)}"
  }
}

resource "aws_ecr_repository_policy" "repo_policy_allowed_accounts" {
  count = "${length(var.list_of_images)}"
  repository = "${element(aws_ecr_repository.images.*.id, count.index)}"
  count = "${length(var.list_of_allowed_accounts)}"
  policy = "${data.template_file.ecr_policy_allowed_accounts.rendered}"
}

This is a bash equivalent of what I am trying to do.

for image in alpine java jenkins
do 
  for account_id in 111111111 2222222
  do 
    // call template here using variable 'account_id' and 'image'
  done
done
count terraform
