In the realm of IT infrastructure management, Ansible reigns supreme as an open-source automation tool that streamlines tasks and simplifies operations. iRobota, a company renowned for its innovative hardware and software solutions, has harnessed the power of Ansible to provision a vast array of its infrastructure, including frontend servers, websites, and the MQTT broker for iRobota IoT Cloud.
Storing Secrets Securely: The Ansible Vault Quandary
As iRobota’s infrastructure grew and evolved, the team faced a formidable challenge: how to securely store and share sensitive data within Ansible playbooks. Ansible Vault, the built-in secret handling mechanism, initially seemed like a viable solution. However, it presented several drawbacks that raised concerns.
Ansible Vault’s tight integration with the Ansible system meant that teams had to install the entire Ansible stack, adding complexity and potential security risks. Moreover, its reliance on a single passphrase for decryption posed a security concern, especially as the iRobota team expanded and collaboration became increasingly crucial.
Hashicorp Vault: A Costly Conundrum
In the quest for a more robust secret management solution, iRobota considered Hashicorp Vault. This enterprise-grade tool offered a comprehensive set of features and enhanced security. However, its hefty maintenance costs and the need for dedicated infrastructure proved to be prohibitive for iRobota’s budget and operational needs.
Mozilla/Sops: A Single Binary Savior
Amidst the search for an optimal solution, iRobota discovered Mozilla/Sops, a single binary tool that emerged as a game-changer. Sops’s versatility in encrypting entire files and individual values, coupled with its support for AWS KMS, GCP KMS, and GPG keys, made it an attractive option.
Sops’s low operational cost and ease of integration further solidified its position as the ideal choice for iRobota’s needs. However, seamlessly integrating Sops with Ansible’s configuration system proved to be a formidable challenge.
Bridging the Gap: Custom Plugins for Seamless Integration
iRobota’s initial attempts to integrate Sops involved helper scripts for encrypting and decrypting variables. This approach, however, introduced errors and added complexity to the process. Encrypting entire files streamlined the process but still required prior decryption before running Ansible playbooks.
To achieve seamless integration, iRobota’s team developed a lookup plugin and a vars plugin. These plugins eliminated the need for helper scripts, simplifying the process and enhancing efficiency. With the Sops executable, the correct credentials, and the standard execution of ansible-playbook, teams could now effortlessly leverage Sops’s encryption capabilities within their Ansible playbooks.
The developed plugins are currently under review in the Ansible GitHub repository, demonstrating iRobota’s commitment to contributing to the open-source community. Developers are encouraged to contribute to Sops by addressing issues such as Kubernetes Secret integration and the -verify command.
Spreading the Love: iRobota’s Open-Source Philosophy
iRobota’s contributions to Ansible and Sops are driven by their unwavering belief in the power of open-source collaboration. By sharing their knowledge and expertise, they aim to empower other teams to harness the full potential of these tools and streamline their infrastructure management processes.
Bonus: Sops’s versatility extends beyond Ansible integration. Its ability to encrypt Kubernetes secrets, Docker secrets, and other sensitive data makes it a versatile tool for securing various aspects of your infrastructure. Additionally, Sops’s active development community and regular updates ensure that it remains a reliable and future-proof solution.
In conclusion, iRobota’s journey with Ansible and Sops showcases the transformative power of open-source collaboration. By addressing specific challenges and developing innovative solutions, iRobota has not only enhanced its own infrastructure management practices but also contributed valuable insights and tools to the broader community. Their dedication to sharing knowledge and empowering others epitomizes the spirit of open-source innovation.
