In 2018, Docker marked its fifth year in production amid a rapidly evolving landscape for container technology, where it played a pivotal role in popularizing containers and enabling their integration into DevOps practices through lightweight, portable, and self-sufficient containers. Despite facing challenges from emerging container orchestration platforms like Kubernetes, which has gained dominance, Docker adapted by integrating Kubernetes into its Docker Enterprise 2.0, indicating a strategic shift to align with industry trends. As DockerCon 2018 approached, the company experienced significant organizational changes, including the departure of co-founder and CTO Solomon Hykes, yet continued to thrive with substantial investments and a robust user community. Although questions about Docker's strategic direction and the impact of serverless computing remain, studies suggest that container adoption is on the rise, providing Docker with a strong foothold in the market and a cautiously optimistic outlook for the future.
