What is a resource?
Resources are dependencies of an app that communicate with it over the network and run software outside the scope of your team’s focus.
You can create resources using the
convox resources create command.
This will provision the appropriate AWS service and associate it with your active Convox Rack.
Creation can take up to 15 minutes. To check the status, use
convox resources info. You can also view the resource in the appropriate section of your AWS console (RDS for postgres and mysql, etc).
For advanced creation options, see the documentation for the specific resource type in the sidebar on the left.
Resource Status and Information
To see relevant info about a resource, use the
convox resources info command:
$ convox resources info memcached-5864 Name memcached-5864 Status running Exports URL: dev-ca-m3z4ik3n7bej.77prpt.cfg.use1.cache.amazonaws.com:11211
Accessing the resource
Via AWS console
You can view AWS resources in your AWS console, where they will have their own CloudFormation stack. For example, mysql resources are visible in your RDS Console.
If you don’t see what you expect, check that the correct geographic region is active.
Resources are generally configured so they are not accessible from the public internet (when possible). You can get proxy access with the
convox resources proxy command, e.g.:
$ convox resources proxy mysql-4624
For details, see convox resources proxy.
For some types of resources, the username and password are contained in the resource URL, which can be retrieved by running
convox resources info <resource name>.
For example, below we can see the RDS credentials embedded in a
mysql resource URL:
URL: mysql://app:firstname.lastname@example.org:3306/app ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^^^^^^
Connecting the resource to your app
Via environment variables
You can add this URL as an environment variable to any application with
convox env set:
$ convox env set MEMCACHED_URL='dev-ca-m3z4ik3n7bej.77prpt.cfg.use1.cache.amazonaws.com:11211' --app example-app
convox resource link
To forward logs from an application to a syslog forwarder use
convox resources link:
$ convox resources link syslog-3785 --app example-app Linked syslog-3786 to example-app
Note: This is currently only supported with
syslog resources. To link other resource types, use
convox env set as described above.
A few types of resources can be updated. For instance, to modify the URL of a syslog resource that has
example.com as the URL, run
convox resources update <resource name> --param=new_value:
$ convox resources update syslog-3165 --url=example.net Updating syslog-3165 (url="example.com")...UPDATING $ convox resources info syslog-3165 Name syslog-3165 Status updating Exports URL: example.net
Scaling down unused services
If you’ve replaced a service with a resource, you’ll want to be sure to scale the unused service down to
-1 so it doesn’t create unnecessary AWS resources in production.
To delete a resource, use the
convox resources delete command:
$ convox resources delete memcached-5864 Deleting memcached-5864... DELETING
Deleting the resource will take several minutes.
This action will cause an unrecoverable loss of data.
