# vmpooler-provider-aws
# vmpooler-provider-aws
This is a provider for [VMPooler](https://github.com/puppetlabs/vmpooler) allows using aws to create instances, disks,
snapshots, or destroy instances for specific pools.
## Usage
Include this gem in the same Gemfile that you use to install VMPooler itself and then define one or more pools with the `provider` key set to `aws`. VMPooler will take care of the rest.
See what configuration is needed for this provider in the [example file](https://github.com/puppetlabs/vmpooler-provider-aws/blob/main/vmpooler.yaml.example).
Examples of deploying VMPooler with extra providers can be found in the [puppetlabs/vmpooler-deployment](https://github.com/puppetlabs/vmpooler-deployment) repository.
aws authorization is handled via two required ENV vars
1. ABS_AWS_ACCESS_KEY
2. ABS_AWS_SECRET_KEY
### Provisioning the new nodes
When you add the pool config `provision: true` to a pool, the new VMs will also get initialized with extra steps to setup the sshd config via NET:SSH
These steps expect two environment vars
1. ROOT_KEYS_SCRIPT: (optional) the URI location of a script (eg https in github) that will be run to setup keys. If not set, this will be skipped
2. KEY_FILE_LOCATION: (required) the location on local disk where the ssh key resides for VMPooler to connect via SSH to the EC2 node
### DNS
AWS will setup a private ip and private dns hostname for the VM once running. Optionally we can setup a human readable DNS entry to resolve the VMPooler provider `spicy-proton` fqdn
DNS is integrated via Google's CloudDNS service. To enable, a CloudDNS zone name must be provided in the config (see the example yaml file dns_zone_resource_name)
An A record is then created in that zone upon instance creation with the VM's internal IP, and deleted when the instance is destroyed.
### Labels
This provider adds tags to all resources that are managed
|resource|labels|note|
|---|---|---|
|instance|vm=$vm_name, pool=$pool_name|for example vm=foo-bar, pool=pool1|
|disk|vm=$vm_name, pool=$pool_name|for example vm=foo-bar and pool=pool1|
|snapshot|snapshot_name=$snapshot_name, vm=$vm_name, pool=$pool_name| for example snapshot_name=snap1, vm=foo-bar, pool=pool1|
Also see the usage of vmpooler's optional purge_unconfigured_resources, which is used to delete any resource found that
do not have the pool label, and can be configured to allow a specific list of unconfigured pool names.
### Pre-requisite
- An IAM user must exist in the target AWS account with permissions to create, delete vms etc
- if using DNS, a DNS zone needs to be created in CloudDNS, and configured in the provider's config section with the name of that zone (dns_zone_resource_name). When not specified, the DNS setup and teardown is skipped.

:providers:
# :providers:
#
# This section contains the VM providers for VMs and Pools
# The currently supported backing services are:
# - vsphere
# - dummy
# - gce
# - aws
#
# - provider_class
# For multiple providers, specify one of the supported backing services (vsphere or dummy or gce or aws)
# (optional: will default to it's parent :key: name eg. 'aws')
#
# - purge_unconfigured_resources
# Enable purging of VMs, disks and snapshots
# By default will purge resources in the project without a "pool" label, or a "pool" label with the value for an unconfigured pool
# An optional allowlist can be provided to ignore purging certain VMs based on pool labels
# Setting this on the provider will enable purging for the provider
# Expects a boolean value
# (optional; default: false)
#
# - resources_allowlist
# For GCE: Specify labels that should be ignored when purging VMs. For example if a VM's label is
# set to 'pool' with value 'donotdelete' and there is no pool with that name configured, it would normally be purged,
# unless you add a resources_allowlist "donotdelete" in which case it is ignored and not purged.
# Additionally the "" (empty string) has a special meaning whereas VMs that do not have the "pool" label are not purged.
# Additionally if you want to ignore VM's with an arbitrary label, include it in the allow list as a string with the separator "="
# between the label name and value eg user=bob would ignore VMs that include the label "user" with the value "bob"
# If any one of the above condition is met, the resource is ignored and not purged
# This option is only evaluated when 'purge_unconfigured_resources' is enabled
# Expects an array of strings specifying the allowlisted labels by name. The strings should be all lower case, since
# no uppercase char is allowed in a label
# (optional; default: nil)
#
# If you want to support more than one provider with different parameters you have to specify the
# backing service in the provider_class configuration parameter for example 'vsphere' or 'dummy'. Each pool can specify
# the provider to use.
#
# Multiple providers example:
:aws1:
provider_class: 'aws'
zone: 'us-west-2b'
region: 'us-west'
:aws2:
provider_class: 'aws'
zone: 'us-west-2b'
region: 'us-west'
resources_allowlist:
- "user=bob"
- ""
- "custom-pool"
# :aws:
#
# This section contains the global variables for the aws provider
# some of them can be overwritten at the pool level
#
# Available configuration parameters:
#
# - region
# The AWS region name to use when creating/deleting resources
# (required)
# - zone
# The AWS zone name to use when creating/deleting resources (vms, disks etc)
# Can be overwritten at the pool level
# (required)
# - amisize
# The AMI machine type to use eg a1.large
# Can be overwritten at the pool level
# (required)
# - volume_size
# A custom root volume size to use in GB, the default is whatever the default for the AMI used is
# (optional)
# - dns_zone_resource_name
# The name given to the DNS zone ressource. This is not the domain, but the name identifier of a zone eg example-com
# (optional) when not set, the dns setup / teardown is skipped
# - domain
# Overwrites the global domain parameter. This should match the dns zone domain set for the dns_zone_resource_name.
# It is used to infer the domain part of the FQDN ie $vm_name.$domain
# When setting multiple providers at the same time, this value should be set for each GCE pools.
# (optional) If not explicitely set, the FQDN is inferred using the global 'domain' config parameter
# Example:
:aws:
region: 'us-west'
zone: 'us-west-2b'
amisize: 'a1.small'
volume_size: '10'
dns_zone_resource_name: 'subdomain-example-com'
domain: 'subdomain.example.com'
# :pools:
#
# This section contains a list of virtual machine 'pools' for vmpooler to
# create and maintain.
#
# Available configuration parameters (per-pool):
#
# - name
# The name of the pool.
# (required)
#
# - alias
# Other names this pool can be requested as.
# (optional)
#
# - template
# The template or virtual machine target to spawn clones from, in AWS this means an AMI id.
# (required)
#
# - size
# The number of waiting VMs to keep in a pool.
# (required)
#
# - provider
# The name of the VM provider which manage this pool. This should match
# a name in the :providers: section above e.g. vsphere
# (required; will default to vsphere for backwards compatibility)
# If you have more than one provider, this is where you would choose which
# one to use for this pool
#
# - timeout
# How long (in minutes) before marking a clone in 'pending' queues as 'failed' and retrying.
# This setting overrides any globally-configured timeout setting.
# (optional; default: '15')
#
# - ready_ttl
# How long (in minutes) to keep VMs in 'ready' queues before destroying.
# (optional; default: no limit)
#
# - check_loop_delay_min (optional; default: 5) seconds
# - check_loop_delay_max (optional; default: same as check_loop_delay_min) seconds
# - check_loop_delay_decay (optional; default: 2.0) Must be greater than 1.0
# See the :config: section for information about these settings
#
# Provider specific pool settings
#
# EC2 provider
# - zone
# The zone to create the VMs in
# (optional: default is global provider zone value)
# - amisize
# The AMI machine type to use eg a1.large
# (optional: default is global provider amisize value)
# - volume_size
# (optional: default is global provider amisize value)
# - provision
# Set to true to run the extra aws setup steps (SSH, keys etc) once the VM is available
# (optional: default to false)
# Example:
:pools:
- name: 'almalinux-x86_64'
alias: [ 'almalinux-64', 'almalinux-amd64' ]
template: 'ami-foobar1234'
size: 5
timeout: 15
ready_ttl: 1440
provider: aws
zone: 'us-new-zone'
amisize: 'a1.large'
volume_size: '20'
