Creating a CoreOS account activates a License for up to 10 free nodes on a Tectonic cluster.
First, go to https://account.coreos.com/login to sign up for a CoreOS account.
A confirmation email will be sent to the listed account. Check your inbox for an email from CoreOS Support, and click Verify Email.
Log in to complete registration and access the account Overview page, which lists available CoreOS products.
Click Free for use up to 10 nodes below Tectonic, enter your contact information, and click Get License for 10 nodes to complete the registration process. Once complete, the Overview page will list active subscriptions, and provide access to your CoreOS License and Pull Secret.
The CoreOS License and Pull Secret are required to install Tectonic and access container images for CoreOS products.
To obtain these files, log in to your CoreOS account, and click the buttons to Download CoreOS License and Download Pull Secret. Then, provide them when requested during the installation process.
