The announcement of the end of public image distribution by Bitnami marks more than just an operational change. It is a clear signal that the cloud native world is recognizing a technical debt that has accumulated over the years: neglecting security at the foundational layer of container infrastructure.

For a long time, public images have been used as a de facto standard. Docker Hub, Bitnami, and other providers facilitated access to packaged applications that were ready to use and seemingly trustworthy. This model offered convenience and speed but masked an invisible cost. There was no clarity about who built these images, which packages were included, how they were maintained, or how often they were patched. By delegating this responsibility, many companies took on significant risks without realizing it.

Supply chain as a critical point

Recent years have made it evident that the software supply chain is one of the main vectors of attack. Cases of injecting malicious code into packages, mining cryptocurrencies in clusters, and leaking sensitive data have shown that blindly trusting public images compromises security and governance. The problem is not limited to known vulnerabilities. It extends to the lack of traceability and robust controls over each component that reaches production.

Keeping images secure, free from vulnerabilities, and continuously updated is a complex and costly process. It is estimated that more than 130 new vulnerabilities are recorded daily across different technologies. For each fix, screening, rebuilding, and validation are required. The effort is continuous and consumes time and resources from specialized teams.

The real cost of images

With the end of public images, reality sets in: either companies invest in internal teams to maintain and harden their own images or hire specialized vendors that offer this service in a controlled and auditable manner. Both paths have costs but differ in the scale of investment. Sustaining the internal updating of complex stacks like Prometheus, Grafana, Istio, Nginx, RabbitMQ, Redis, or Elasticsearch is not viable for most organizations. The alternative is to rely on companies that take on this responsibility and ensure consistent, secure, and audited images.

This change is not just about Bitnami. It is about the entire container ecosystem. The era when security was set aside in favor of scalability has ended. Now, governance over images and container operating systems needs to be treated as a strategic priority.

Conclusion

The end of free public images does not mean the end of innovation. On the contrary, it represents a necessary maturity. The community needed a decade to realize that convenience cannot come at the cost of security. From now on, the debate is no longer whether we should invest in maintaining secure images, but how to do so efficiently.

Companies that understand this movement and adjust their practices will come out ahead. Those that insist on treating images as an operational detail risk turning vulnerabilities into serious incidents. The message is clear: the future of containers lies in the conscious control of the entire software supply chain.
