Kops download config file

A Route53 hosted zone can serve subdomains. Your hosted zone could be useast1. Let's assume you're using dev. You create that hosted zone using the normal process , or with a command such as aws route53 create-hosted-zone --name dev. You must then set up your NS records in the parent domain, so that records in the domain will resolve. Here, you would create NS records in example.

If it is a root domain name you would configure the NS records at your domain registrar e. Verify your route53 domain setup it is the 1 cause of problems!

You can double-check that your cluster is configured correctly if you have the dig tool by running:. To do this, it must keep track of the clusters that you have created, along with their configuration, the keys they are using etc. This information is stored in an S3 bucket. S3 permissions are used to control access to the bucket. Multiple clusters can use the same S3 bucket, and you can share an S3 bucket between your colleagues that administer the same clusters - this is much easier than passing around kubecfg files.

But anyone with access to the S3 bucket will have administrative access to all your clusters, so you don't want to share it beyond the operations team. So typically you have one S3 bucket for each ops team and often the name will correspond to the name of the hosted zone above! The default for the s3 store is using AWS credentials. It defaults to us-east The state store can easily be moved to a different s3 bucket.

The steps for a single cluster are as follows:. Many enterprises prefer to run many AWS accounts. In these setups, having a shared cross-account S3 bucket for state may make inventory and management easier. In order to achieve this, you first need to let Account A access the s3 bucket. This is done by adding the following bucket policy on the S3 bucket:.

The swift store can be configured by providing your OpenStack credentials and configuration in environment variables:.

The state store config for google cloud will be derived by the google storage client SDK as follows:. It is currently an experimental feature and you have to enable the VFSVaultSupport feature flag to enable it. The goal of the vault store is to be a safe storage for the kOps keys and secrets store. Among other things, etcd-manager is unable to read VFS control files from vault.

Vault also cannot be used as backend for etcd backups. Each of the paths specified above can be configurable, but they must be unique across all clusters. You can also not use the same path as both stateStore and keyStore.

After launching your cluster you need to add the cluster roles to Vault, binding them to the cluster's IAM identity and granting them access to the appropriate secrets and keys. The nodes will wait until they can authenticate before completing provisioning.

Note that contrary to the S3 state store, kOps will not provision any policies for you. You have to provide roles for both operators and nodes.

Note that if you re-provision your cluster, you need to re-run the above in order for Vault to update the role internal IDs. As of now the following state stores are supported:. The state store is just files; you can copy the files down and put them into git or your preferred version control system. One of the most important files in the state store is the top-level config file. When you run kops create cluster , we create a state store entry for you based on the command line options you specify.

The configuration you specify on the command line is actually just a convenient short-cut to manually editing the configuration.

Options you specify on the command line are merged into the existing configuration. If you want to configure advanced options, or prefer a text-based configuration, you may prefer to just edit the config file with kops edit cluster. Because the configuration is merged, this is how you can just specify the changed arguments when reconfiguring your cluster - for example just kops create cluster after a dry-run.

It is permitted so as to enable review workflows. For example, in a review workflow, it can be desirable to check a set of untrusted changes before they are applied to real infrastructure.

If submitted untrusted changes to configuration files are naively run by kops replace , then kOps would overwrite the state store used by production infrastructure with changes which have not yet been approved.

This is dangerous. Instead, a review workflow may download the contents of the state bucket to a local directory using aws s3 sync or similar , set the state store to the local directory e. This allows the review process to make changes to a local copy of the state bucket, and check those changes, without touching the production state bucket or production infrastructure. Trying to use a local filesystem state store for real i. In theory, a cluster administrator could put the state store on a shared NFS volume that is mounted to the same directory on each of the nodes; however, that use case is not supported as of yet.
