If you’re facing such an error:

UnauthorizedOperation: You are not authorized to perform this operation.

Run terraform like this:

TF_LOG=1 terraform apply

And this will most likely help you further with your debugging.

If you receive something like this as a result of an aws operation:

You are not authorized to perform this operation. Encoded authorization failure message: (redacted)

Then, you can decode it like this:

aws sts decode-authorization-message --encoded-message redacted

To have the above command work, make sure your user has the sts:DecodeAuthorizationMessage grant.

Received an error like this in the console:

Could not load module WebAssist.Repo, got: badfile
[error] beam/beam_load.c(1278): Error loading module 'Elixir.WebAssist.Repo':
  module name in object code is Elixir.Webassist.Repo

Turns out, the module name was Webassist, and not WebAssist.

Turns out the requests coming from Amazon SNS have

1

Content-Type: text/plain

amazon_params = JSON.parse(request.raw_post)

Notice that we’re using

1

raw_post

I had the following in my sshd_config:

Match Group myftpgroup
  Allowtcpforwarding no
  Chrootdirectory %h
  Forcecommand internal-sftp

Imagining a user called john, this was the setup:

• /home was owned by root
• /home/john was owned by root
• the files inside john were john’s own files

With all these in place, this was what I received when sftp-ing:

sftp> put README.md
Uploading README.md to /new/README.md
remote open("/new/README.md"): Permission denied

Turns out, it was caused by selinux, and the fix was to run this cmd:

setsebool -P ssh_chroot_rw_homedirs on

Assuming your user name is john, pasting the contents of the user’s public key in

1

/home/john/.ssh/authorized_keys

If you have untracked files that you’d like ignored, add them to

1

.git/info/exclude

To be able to do a pull on a newly created machine, without you having to do an initial ssh to github, or some other host, you can do this in a recipe:

ssh_known_hosts_entry 'github.com'

This comes from the ssh_known_hosts cookbook
