Using a custom snapshot
Vultr supports creating custom snapshots from public raw images.
These steps show how to download a FCOS image and upload it to an existing storage bucket, in order to create a snapshot from that.
See https://www.vultr.com/docs/vultr-object-storage[Vultr documentation] for further details on how to create a bucket and configure `s3cmd` to use it.
Creating a snapshot
Fedora CoreOS comes in three streams, with different update schedules per stream. These steps show the `stable` stream as an example, but can be used for other streams too.
Fetch the latest image suitable for your target stream (or https://fedoraproject.org/coreos/download/[download and verify] it from the web).
STREAM='stable'
coreos-installer download -s "${STREAM}" -p vultr -f raw.xz --decompress
https://www.vultr.com/docs/how-to-use-s3cmd-with-vultr-object-storage[Use s3cmd to upload] the raw image to your bucket, and note its public URL.
BUCKET='my-bucket'
FCOS_VERSION='...'
s3cmd put --acl-public "fedora-coreos-${FCOS_VERSION}-vultr.x86_64.raw" "s3://${BUCKET}/"
Create the snapshot from your object URL, and note its ID.
IMAGE_URL='https://...'
VULTR_API_KEY='<token>'
vultr-cli snapshot create-url -u "${IMAGE_URL}"
You'll need to wait for the snapshot to finish processing before using it. Monitor with `*vultr-cli snapshot list*`.
Launching an instance from a snapshot
You can now create a FCOS Vultr instance using the snapshot ID above.
This example creates a 2 vCPU, 4GB RAM instance named `instance1` in the New Jersey region. Use `vultr-cli regions list` and `vultr-cli plans list` for other options.
NAME='instance1'
SNAPSHOT_ID='...'
REGION='ewr'
PLAN='vc2-2c-4gb'
vultr-cli instance create --region "${REGION}" --plan "${PLAN}" \
--snapshot "${SNAPSHOT_ID}" --label "${NAME}" --host "${NAME}" \
--userdata "$(cat example.ign)"
While the Vultr documentation mentions `cloud-init` and scripts, FCOS does not support `cloud-init` or the ability to run scripts from user-data. It accepts only Ignition configuration files.
You can find out the instance's assigned IP by running `vultr-cli instance list`.
You now should be able to SSH into the instance using the associated IP address.
Example connecting
ssh core@<ip address>
