Weave vs Kustomize: What are the differences?

What is Weave? Weave creates a virtual network that connects Docker containers deployed across multiple hosts. Weave can traverse firewalls and operate in partially connected networks. Traffic can be encrypted, allowing hosts to be connected across an untrusted network. With weave you can easily construct applications consisting of multiple containers, running anywhere.

What is Kustomize? Kubernetes native configuration management. It introduces a template-free way to customize application configuration that simplifies the use of off-the-shelf applications. Now, built into kubectl as apply -k.

Weave and Kustomize can be primarily classified as "Container" tools.

Some of the features offered by Weave are:

• Virtual Ethernet Switch
• Application isolation
• Security

On the other hand, Kustomize provides the following key features:

• Purely declarative approach to configuration customization
• Natively built into kubectl
• Manage an arbitrary number of distinctly customized Kubernetes configurations

Weave is an open source tool with 5.88K GitHub stars and 583 GitHub forks. Here's a link to Weave's open source repository on GitHub.
