Is docker free?
On August 31, 2021, Docker announced that Docker Desktop will be transformed into Docker Personal, which will only be provided for free to small businesses, individuals, education, and non-commercial open source projects use. For other use cases, a paid subscription is required.
That said, it remains free for small businesses (less than 250 employees and less than $10 million in annual revenue), personal use, education, and non-commercial open source projects.
Otherwise a minimum fee of $5 per person per month is required.
Docker offers three paid subscription plans: Pro, Team, and Business.
The more expensive plans provide more services. Docker Business can provide several functions including centralized management, single sign-on and enhanced security. Users can set what developers are allowed to access on a centralized control panel. There is also centralized SaaS-based management with the ability to control the configuration of CPU usage, memory, ports and firewall access.
In general, Docker Business mainly wants to help enterprises better manage the Docker development environment.
Regarding this change, Docker officials mainly gave two reasons:
Now the company wants to solve the security risks in the software supply chain
The company needs to develop a Viable business model
Having said so much, what impact does it have on us developers?
I don’t think it has any bad influence.
1. Because even if there is a fee, it is paid by the big company.
2. Even if you provide money, it is only a drop in the bucket for a large company.
3. Docker Desktop is only available for Windows and Mac. If you use Linux, it will not be affected at all.
4. If you are using the community version of DockerCE, it is not affected by Docker Company in any way.
What I want to talk about is DockerHub. DockerHub is a public image storage service provided by Docker Company. It can be regarded as the GitHub of Docker images. It is not open source and is decided by Docker Company. Anyone who has used Docker knows that Docker images can easily become very large. The corresponding DockerHub storage space has skyrocketed to more than 15 PB (1PB = 1048576GB). Docker recently added a new terms of service, giving it the right to delete Inactive images may be deleted if they are inactive for half a year. You can renew them by paying money. If there is an image uploaded to DockerHub, remember to push or pull it in time.
In addition, Docker charging is also a good thing, which shows that Docker has been fully trusted by businesses. With money, Docker can provide better services, and enterprises can use it with confidence. There may also be some room for alternatives to Docker that can meet different levels of needs.
A major trend now is the paid subscription model of software. There is a consensus on software payment, which is good for developers. Software can directly bring economic benefits instead of relying on advertising. The value of programmers and society The status will also become higher and higher.
