As of v1.3.4, LambdaStack requires you to change the following attributes in the either the minimal or full configuration YAML. Beginning in v2.0, you will have the option to pass in these parameters to override whatever is present in the yaml file. v2.0 is in active development
All but the last two options are defaults. The last two are
AWS Secret- these two are required
Attributes to change for the minimal configuration After you run `lambdastack init -p aws -n
prefix: staging- Staging is a default prefix. You can use whatever you like (e.g.,
production). This value can help group your AWS clusters in the same region for easier maintenance
name: ubuntu- This attribute is under
specification.admin_user.name. For ubuntu on AWS the default user name is
ubuntu. For Redhat we default to
key_path: lambdastack-operations- This is the default SSH key file(s) name. This is the name of your SSH public and private key pairs. For example, in this example, one file (private one) would be named
lambdastack-operations. The second file (public key) typically has a
.pubsuffix such as
use_public_ips: True- This is the default public IP value. Important, this attribute by default allows for AWS to build your clusters with a public IP interface. We also build a private (non-public) interface using private IPs for internal communication between the nodes. With this attribute set to
publicit simply allows you easy access to the cluster so you can SSH into it using the
nameattribute value from above. This is
NOT RECOMMENDEDfor sure not in production and not as a general rule. You should have a VPN or direct connect and route for the cluster
region: us-east-1- This is the default region setting. This means that your cluster and storage will be created in AWS'
us-east-1region. Important - If you want to change this value in any way, you should use the
full configurationand then change ALL references of region in the yaml file. If you do not then you may have services in regions you don't want and that may create problems for you
key: XXXXXXXXXX- This is very important. This, along with
secretare used to access your AWS cluster programmatically which LambdaStack needs. This can be found at
specification.cloud.credentials.key. This can be found under your AWS Account menu option in Security Credentials
secret: XXXXXXXXXXXXX- This is very important. This, along with
keyare used to access your AWS cluster programmatically which LambdaStack needs. This can be found at
specification.cloud.credentials.secret. This can be found under your AWS Account menu option in Security Credentials. This can only be seen at the time you create it so use the download option and save the file somewhere safe. DO NOT save the file in your source code repo!
Now that you have made your changes to the
lambdastack apply -f build/<whatever you name your cluster>/<whatever you name your cluster>.yml. Now the building of a LambdaStack cluster will begin.
Apply option will generate a final
manifest.yml file that will be used for Terraform, Ansible and LambdaStack python code. The
manifest.yml will combine the values from below plus ALL yaml configuration files for each service.
