Protect resources from deletion with a protection tag, do_no_delete.

NOTE: this project is used in Qovery's production environment

Requirements

In order to make pleco check and clean expired resources you need to set the following environment variables:

For AWS

$ export AWS_ACCESS_KEY_ID=<access_key>
$ export AWS_SECRET_ACCESS_KEY=<secret_key>

For Scaleway

$ export SCW_ACCESS_KEY=<access_key>
$ export SCW_SECRET_KEY=<secret_key>
$ export SCW_VOLUME_TIMEOUT=<delay_before_detached_volume_deletion_in_hours_since_last_update> # default is 2 hours

For Digital Ocean

$ export DO_API_TOKEN=<your_do_api_token>
$ export DO_SPACES_KEY=<your_do_api_key_for_spaces>
$ export DO_SPACES_SECRET=<your_do_api_secret_for_spaces>
$ export DO_VOLUME_TIMEOUT=<delay_before_detached_volume_deletion_in_hours_since_creation> # default is 2 hours

Basic command

A pleco command has the following structure:

pleco start <cloud_provider> [options]

General options

Connection Mode

You can set the connection mode with:

--kube-conn, -k <connection mode>

Default is "in"

Debug Level

You can set the debug level with:

--level <log level>

Default is "info"

Check's interval

You can set the interval between two pleco's check with:

--check-interval, -i <time in seconds>

Default is "120"

Dry Run

If you disable dry run, pleco will delete expired resources. If not it will only tells you how many resources are expired.

You can disable dry-run with:

--disable-dry-run, -y

Default is "false"

AWS options

Region selector

When pleco's look for expired resources, it will do it by aws region.

You can set region(s) with:

--aws-regions, -a <region(s)>

For example:

-a eu-west-3,us-east-2

Resources Selector

When pleco is running you have to specify which resources expiration will be checked.

Here are some of the resources you can check:

--enable-eks, -e # Enable EKS watch
--enable-iam, -u # Enable IAM watch (groups, policies, roles, users)

Example

pleco start aws --level debug -i 240 -a eu-west-3 -e -r -m -c -l -b -p -s -w -n -u -z -o -y

Scaleway options

Region selector

When pleco's look for expired resources, it will do it by scaleway zone.

You can set zone(s) with:

--scw-zones, -a <zone(s)>

For example:

-a fr-par-1

Resources Selector

When pleco is running you have to specify which resources expiration will be checked.

Here are some of the resources you can check:

--enable-cluster, -e # Enable cluster watch

Example

pleco start scaleway --level debug -i 240 -a fr-par-1 -e -r -o -l -b -s -p -y

Digital Ocean options

Region selector

When pleco's look for expired resources, it will do it by digital ocean region.

You can set zone(s) with:

--do-regions, -a <region(s)>

For example:

-a nyc3

Resources Selector

When pleco is running you have to specify which resources expiration will be checked.

Here are some of the resources you can check:

--enable-cluster, -e # Enable cluster watch

Example

pleco start do --level debug -i 240 -a nyc3 -e -r -s -l -b -y
