Compute the number of hours used by a customer for a given date range in Zendesk
#!/bin/bash
# 1. Make sure obtain an API Token
# 2. This has only been validated to work with ZenDesk agents, not end users
# 3. Look up the customer's org ID by querying https://gruntwork.zendesk.com/api/v2/organizations.json
# 4. Look up the ZenDesk custom Field ID that stores the number of hours used by querying a complete ticket and inspecting the JSON output
# 5. This script all automatically sum the total of all numbers in the given month and ignore empty numbers.

Healthline Gist

HealthLine Temp AWS Infrastructure Instructions

We setup a limited version of the infrastructure needed by HealthLine in AWS using Terraform.

Environments

This infrastructure has two environments:

  • mgmt: Contains a Bastion Host where you SSH to get access to everything else
  • stage: Contains an ECS Cluster running the gruntwork-sample-app

Play Framework Vulnerability 2017.04.07

April 7th 2017

Description

A deserialization vulnerability has been found in the socket appender and socket receiver in Logback, which is used by Play. This affects all versions of Play from 2.0.0 through 2.5.13.

Play includes integration with Logback through SLF4J. Logback has functionality that enables logging events to be sent over a network, using Java Serialization.

Using Logback in Play itself does not result in vulnerability as per the default Play configuration, but if Logback has been specifically configured to use SocketAppender or ServerSocketReceiver, then Play is vulnerable.

Workflow for Tesla

To deploy a change to an app to stage, in the current workflow, you'd do the following:

  1. Accept our previous github invitation for user l85m at https://github.com/gruntwork-io
  2. git clone https://github.com/gruntwork-io/sample-app-tesla && cd sample-app-tesla
  3. docker-compose up
  4. Open http://localhost:3000 to see the app.
  5. Make whatever changes you want and refresh your browser. A good file to change is app/index.html.
  6. git commit -am "some commit message"
  7. git push
  8. Normally, this would kick off a build in Jenkins which would automatically push a new Docker image to ECR and then auto-deploy to stage or prod. But because we haven't configured Jenkins yet, you would manually deploy as follows:
