How do I encrypt ETCD?

Access to the cluster as a user with the cluster-admin role.

  1. Modify the APIServer object: $ oc edit apiserver.
  2. Set the encryption field type to identity : spec: encryption: type: identity.
  3. Save the file to apply the changes. The decryption process starts.
  4. Verify that etcd decryption was successful.

How are secrets stored in ETCD?

Use SSL/TLS—when running etcd in a cluster, you must use secure peer-to-peer communication. You can’t share the manifest file or check it into a repo—commonly, secrets are configured using JSON or YAML files, with the secret encoded in base64. If you share or check in these manifest files, the secret is compromised.

How is ETCD data stored?

When first started, etcd stores its configuration into a data directory specified by the data-dir configuration parameter. Configuration is stored in the write ahead log and includes: the local member ID, cluster ID, and initial cluster configuration.

What is the best way to encrypt configuration data and use it with in a pod?

Encrypting your data

  1. Generate a 32 byte random key and base64 encode it. If you’re on Linux or macOS, run the following command:
  2. Place that value in the secret field.
  3. Set the –encryption-provider-config flag on the kube-apiserver to point to the location of the config file.
  4. Restart your API server.

How do I find my Kubernetes secret password?

Retrieving the RabbitMQ™ password in Kubernetes™

  1. From a command line window, run the following command to retrieve the data contained in the secret. kubectl get secret velocity-rabbitmq-secret -o yaml.
  2. On the password line, copy the password. The password is Base64 encrypted.
  3. Use a Base64 decoder to decode the password.

Does Kubernetes encrypt secrets at rest?

By default, the secret data is stored in plaintext in etcd. Kubernetes does support encryption at rest for the data in etcd, but the key for that encryption is stored in plaintext in the config file on the master nodes.

How can we protect our secrets?

The following tips are for businesses that wish to protect their trade secrets:

  1. Identify What Needs Protection.
  2. Label Documents That Contain Protected Information.
  3. Monitor Where Information is Stored.
  4. Secure Computers.
  5. Maintain Secrecy With Outside Vendors.
  6. Provide Adequate Security.
  7. Limit Public Access to the Company.

Is ETCD secure?

The etcd members will form a cluster and all communication between members in the cluster will be encrypted and authenticated using the client certificates. The output of etcd will show that the addresses it connects to use HTTPS.

What is stored in ETCD?

Etcd is a crucial component for Kubernetes as it stores the entire state of the cluster: its configuration, specifications, and the statuses of the running workloads.

Where is ETCD config stored?

The etcd configuration files to be preserved are all stored in the /etc/etcd directory of the instances where etcd is running. This includes the etcd configuration file ( /etc/etcd/etcd. conf ) and the required certificates for cluster communication.

What is the difference between ConfigMap and secret?

The major difference is, Secrets store data in base64 format meanwhile ConfigMaps store data in a plain text. If you have some critical data like, keys, passwords, service accounts credentials, db connection string, etc then you should always go for Secrets rather than Configs.

What is ingress in Kubernetes?

In Kubernetes, an Ingress is an object that allows access to your Kubernetes services from outside the Kubernetes cluster. You configure access by creating a collection of rules that define which inbound connections reach which services.

How do I create a secure communication channel in etcd?

To begin, establish secure communication channels by generating a key and certificate pair. For example, use key pairs peer.key and peer.cert for securing communication between etcd members, and client.key and client.cert for securing communication between etcd and its clients.

What is etcd in Kubernetes and how to backup it?

etcd is a consistent and highly-available key value store used as Kubernetes’ backing store for all cluster data. If your Kubernetes cluster uses etcd as its backing store, make sure you have a back up plan for those data. You can find in-depth information about etcd in the offical documentation. Before you begin.

What is etcd and how to restore from a snapshot?

etcd supports restoring from snapshots that are taken from an etcd process of the major.minor version. Restoring a version from a different patch version of etcd also is supported. A restore operation is employed to recover the data of a failed cluster.

What is etcd and how does it work?

etcd is open source, available on GitHub, and backed by the Cloud Native Computing Foundation. etcd is written in Go, which has excellent cross-platform support, small binaries and a great community behind it. Communication between etcd machines is handled via the Raft consensus algorithm.
