AWS playground for OpenBSD kids.
Running whatever is in this repo will propably end up destroying a kitten factory.
- shell access to OpenBSD current >6.5 with vmm(4) support and Internet access
- 3.5GB of free space in ${TMPDIR}
- awscli and vmdktool packages installed
- AWS IAM user with enough permissions (AmazonEC2FullAccess, AmazonS3FullAccess, IAMFullAccess)
- AWS environment variables properly set (when not use root's awscli configuration):
- AWS_CONFIG_FILE
- AWS_DEFAULT_PROFILE (when not using the default profile)
- AWS_SHARED_CREDENTIALS_FILE
- AWS environment variables properly set (when not use root's awscli configuration):
usage: obsd-img-builder.sh
-a "architecture" -- default to "amd64"
-d "description" -- AMI description; defaults to "openbsd-$release-$timestamp"
-i "path to RAW image" -- use image at path instead of creating one
-m "install mirror" -- defaults to installurl(5) or "https://cdn.openbsd.org/pub/OpenBSD"
-n -- only create a RAW image (don't convert to an AMI nor push to AWS)
-r "release" -- e.g "6.5"; default to "snapshots"
-s "image size in GB" -- default to "12"
- arm64 support
- MP support
While a newly built image/AMI will contain a randomized kernel, it is advised to add user-data at first boot that will reboot the instance once the first randomization is done. This is so that every instance will indeed run a different relinked kernel.
