HTTP Proxy Test

Test

1) Proxy setup

Connect to the target device's host OS, and create the system-proxy directory:

mkdir -p /mnt/boot/system-proxy/

imrehg

#the RESIN_API_KEY and RESIN_APP_ID is available in the application container, if enabled
curl -v -X GET \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer ${RESIN_API_KEY}" \
  'https://api.resin.io/v4/service?$filter=application%20eq%20'${RESIN_APP_ID}'&$select=id,service_name'

Supervisor update test through the API

Test

This test checks if the update-resin-supervisor script correctly gets the supervisor information from the API.

• connect to the host OS
• copy and paste the below script into the shell to run it - it will take the device's credentials, calls the API for the supervisor for cross-check, update the API entry for this device, and calls the supervisor updater to check if it finds the updated info.

/*
 * Thread configuration for each thread. Make sure it matches the number above.
 * low_power_mode - This mode will double the cache usage, and double the single thread performance. It will
 *                  consume much less power (as less cores are working), but will max out at around 80-85% of
 *                  the maximum performance.
 *
 * no_prefetch -    Some sytems can gain up to extra 5% here, but sometimes it will have no difference or make
 *                  things slower.
 *
 * affine_to_cpu -  This can be either false (no affinity), or the CPU core number. Note that on hyperthreading
