Before provisioning an FCOS machine, you must have an Ignition configuration file containing your customizations. If you do not have one, see xref:producing-ign.adoc[Producing an Ignition File].
|
|
|
BUCKET='my-bucket'
FCOS_VERSION='...'
s3cmd put -P "fedora-coreos-${FCOS_VERSION}-vultr.x86_64.raw" "s3://{BUCKET}/"
|
|
|
Create the snapshot from your object URL, and note its ID.

|
|
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://getfedora.org/coreos/download/[download and verify] it from the web).
|
|
|
https://www.vultr.com/docs/vultr-object-storage#s3cmd__Example_CLI_tool[Use s3cmd to upload] the raw image to your bucket, and note its public URL.
|
|
|
If you do not want to use Ignition to get started, you can make use of the https://coreos.github.io/afterburn/platforms/[Afterburn support] and provide an SSH key via the cloud provider and continue from there.
|
|
|
IMAGE_URL='https://...'
VULTR_API_KEY='<token>'
vultr-cli snapshot create-url -u "${IMAGE_URL}"
|
|
|
Launching an instance from a snapshot
|
|
|
NAME='instance1'
SNAPSHOT_ID='...'
REGION='ewr'
PLAN='2-1c-1gb'
vultr-cli instance create --region "${REGION}" --plan "${PLAN}" --snapshot "${SNAPSHOT_ID}" --label "${NAME}" --host "${NAME}" --userdata "$(cat example.ign)"

Prerequisites
|
|
|
Provisioning Fedora CoreOS on Vultr
|
|
|
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.
|
|
|
STREAM='stable'
coreos-installer download -s "${STREAM}" -p vultr -f raw.xz --decompress
|
|
|
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.
|
|
|
This example creates a 1 vCPU, 1GB RAM instance named `instance1` in the New Jersey region. Use `vultr-cli regions list` and `vultr-cli plans list` for other options.
|
|
|
This guide shows how to provision new Fedora CoreOS (FCOS) nodes on Vultr. FCOS images are currently not published directly on Vultr, but they can be uploaded as https://www.vultr.com/docs/requirements-for-uploading-an-os-iso-to-vultr[custom images].
|
|
|
Using a custom snapshot
|
|
|
Vultr default firewall does not allow incoming SSH connections. Rules must be adjusted if you wish to reach the instance over SSH.
