After a few moments the Vault cluster should elect a new active primary. The Vault
cluster is now upgraded!
#### Google KMS Auto Unseal
In order to authenticate and use KMS in Google Cloud, Vault Helm needs credentials. The `credentials.json`
file will need to be mounted as a secret to the Vault container.
##### Create the Secret
First, create the secret in Kubernetes:
```bash
kubectl create secret generic kms-creds --from-file=credentials.json
```
Vault Helm will mount this to `/vault/userconfig/kms-creds/credentials.json`.
##### Config Example
The following is an example of how to configure Vault Helm to use Google KMS:
```yaml
global:
enabled: true
image: "vault:1.2.4"
server:
extraEnvironmentVars:
GOOGLE_REGION: <REGION WHERE KMS IS LOCATED>
GOOGLE_PROJECT: <PROJECT NAME>
GOOGLE_APPLICATION_CREDENTIALS: /vault/userconfig/kms-creds/credentials.json
extraVolumes:
- type: "secret"
name: "kms-creds"
ha:
enabled: true
replicas: 3
config: |
ui = true
listener "tcp" {
tls_disable = 1
address = "[::]:8200"
cluster_address = "[::]:8201"
}
seal "gcpckms" {
project = "<NAME OF PROJECT>"
region = "<NAME OF REGION>"
key_ring = "<NAME OF KEYRING>"
crypto_key = "<NAME OF KEY>"
}
storage "consul" {
path = "vault"
address = "HOST_IP:8500"
}
```
#### Amazon EKS Auto Unseal
In order to authenticate and use EKS in AWS, Vault Helm needs credentials. The AWS access key
ID and key will be mounted as secret environment variables in the Vault pods.
##### Create the Secret
First, create a secret with your EKS access key/secret:
```bash
kubectl create secret generic eks-creds\
--from-literal=AWS_ACCESS_KEY_ID="${AWS_ACCESS_KEY_ID?}" \
--from-literal=AWS_SECRET_ACCESS_KEY="${AWS_SECRET_ACCESS_KEY?}"
```
##### Config Example
The following is an example of how to configure Vault Helm to use AWS EKS:
```yaml
global:
enabled: true
image: "vault:1.2.4"
server:
extraSecretEnvironmentVars:
- envName: AWS_ACCESS_KEY_ID
secretName: eks-creds
secretKey: AWS_ACCESS_KEY_ID
- envName: AWS_SECRET_ACCESS_KEY
secretName: eks-creds
secretKey: AWS_SECRET_ACCESS_KEY
ha:
enabled: true
config: |
ui = true
listener "tcp" {
tls_disable = 1
address = "[::]:8200"
cluster_address = "[::]:8201"
}
seal "awskms" {
region = "KMS_REGION_HERE"
kms_key_id = "KMS_KEY_ID_HERE"
}
storage "consul" {
path = "vault"
address = "HOST_IP:8500"
}
```
