You can deploy an additional regional AWS-based cluster to create managed clusters of several provider types or with different configurations.
To deploy an AWS-based regional cluster:
Log in to the node where you bootstrapped a management cluster.
Prepare the AWS configuration for the new regional cluster:
Verify access to the target cloud endpoint from Docker. For example:
docker run --rm alpine sh -c "apk add --no-cache curl; \
curl https://ec2.amazonaws.com"
The system output must contain no error records. In case of issues, follow the steps provided in Troubleshooting.
Change the directory to the kaas-bootstrap folder.
In templates/aws/machines.yaml.template,
modify the spec:providerSpec:value section
by substituting the ami:id parameter with the corresponding value
for Ubuntu 18.04 from the required AWS region. For example:
spec:
providerSpec:
value:
apiVersion: aws.kaas.mirantis.com/v1alpha1
kind: AWSMachineProviderSpec
instanceType: c5d.2xlarge
ami:
id: ami-033a0960d9d83ead0
Also, modify other parameters as required.
Optional. In templates/aws/cluster.yaml.template, modify the default
configuration of the AWS instance types and AMI IDs for further creation
of managed clusters:
providerSpec:
value:
...
kaas:
...
regional:
- provider: aws
helmReleases:
- name: aws-credentials-controller
values:
config:
allowedInstanceTypes:
minVCPUs: 8
# in MiB
minMemory: 16384
# in GB
minStorage: 120
supportedArchitectures:
- "x86_64"
filters:
- name: instance-storage-info.disk.type
values:
- "ssd"
allowedAMIs:
-
- name: name
values:
- "ubuntu/images/hvm-ssd/ubuntu-bionic-18.04-amd64-server-20200729"
- name: owner-id
values:
- "099720109477"
Also, modify other parameters as required.
If you require all Internet access to go through a proxy server,
in bootstrap.env, add the following environment variables
to bootstrap the regional cluster using proxy:
HTTP_PROXY
HTTPS_PROXY
NO_PROXY
Example snippet:
export HTTP_PROXY=http://proxy.example.com:3128
export HTTPS_PROXY=http://user:pass@proxy.example.com:3128
export NO_PROXY=172.18.10.0,registry.internal.lan
The following variables formats are accepted:
Variable |
Format |
|---|---|
|
|
|
Comma-separated list of IP addresses or domain names |
For the list of Mirantis resources and IP addresses to be accessible from the Container Cloud clusters, see Requirements for an AWS-based cluster.
Optional. Configure the regional NTP server parameters to be applied to all machines of regional and managed clusters in the specified region.
In templates/aws/cluster.yaml.template, add the ntp:servers section
with the list of required servers names:
spec:
...
providerSpec:
value:
kaas:
...
regional:
- helmReleases:
- name: aws-provider
values:
config:
lcm:
...
ntp:
servers:
- 0.pool.ntp.org
...
provider: aws
...
Configure the bootstrapper.cluster-api-provider-aws.kaas.mirantis.com
user created in the previous steps:
Using your AWS Management Console, generate the AWS Access Key ID with
Secret Access Key for
bootstrapper.cluster-api-provider-aws.kaas.mirantis.com
and select the AWS default region name.
Export the AWS bootstrapper.cluster-api-provider-aws.kaas.mirantis.com
user credentials that were created in the previous step:
export KAAS_AWS_ENABLED=true
export AWS_SECRET_ACCESS_KEY=XXXXXXX
export AWS_ACCESS_KEY_ID=XXXXXXX
export AWS_DEFAULT_REGION=us-east-2
Export the following parameters:
export KUBECONFIG=<pathToMgmtClusterKubeconfig>
export REGIONAL_CLUSTER_NAME=<newRegionalClusterName>
export REGION=<NewRegionName>
Substitute the parameters enclosed in angle brackets with the corresponding values of your cluster.
Caution
The REGION and REGIONAL_CLUSTER_NAME parameters values
must contain only lowercase alphanumeric characters, hyphens,
or periods.
Note
If the bootstrap node for the regional cluster deployment is not
the same where you bootstrapped the management cluster, also
export SSH_KEY_NAME. It is required for the management
cluster to create a publicKey Kubernetes CRD with the
public part of your newly generated ssh_key
for the regional cluster.
export SSH_KEY_NAME=<newRegionalClusterSshKeyName>
Run the regional cluster bootstrap script:
./bootstrap.sh deploy_regional
Note
When the bootstrap is complete, obtain and save in a secure location
the kubeconfig-<regionalClusterName> file
located in the same directory as the bootstrap script.
This file contains the admin credentials for the regional cluster.
If the bootstrap node for the regional cluster deployment is not
the same where you bootstrapped the management cluster, a new
regional ssh_key will be generated.
Make sure to save this key in a secure location as well.
