Cross account bucket access for IAM roles


This is a little tricky, because it requires several different moving parts, specifically,

  • the lambda task that you want to execute the copy must have IAM access to the bucket in the other account. This is not something that was obvious to me to begin with, although my use case was more complicated.
  • the bucket policy on the destination account must be set to permit your lambda function to write to that bucket. For my special use cases, I have to upload a new bucket policy daily to the receiving buckets. Alternatively, the destination accounts could probably give your a cross-account IAM role to upload the bucket policy yourself.
  • You will likely want to write your objects with the bucket-owner-full-control acl, otherwise, the bucket owner may not be able to download them.

CentOS 7 Kickstart File & How to build an (auto install) ISO

CentOS 7 Kickstart File - HOWTO Build ISO

There is so much documentation online from RedHat and CentOS about this topic - it's sad that I am writing this. But the real state of documentation on this topic (CentOS 7 + KS + ISO = Bootable DVD) is almost non-existent.

I found this:

Which I greatly appreciate and +1, but the documentation is half-baked and there are numerous errors.

Finally... FINALLY! After four days of banging my head, I got this to work. Hopefully someone else will be able to do this in a few hours, instead of blowing their weekend like me. :(

Keep retrying SSH connection until success (Useful for waiting for VMs to boot)
#!/usr/bin/env bash
# Check we've got command line arguments
if [ -z "$*" ] ; then
echo "Need to specify ssh options"
exit 1
# Start trying and retrying
((count = 100))
You can’t perform that action at this time.
