This article will explain in detail what are the three open source container tools for Oracle. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Smith-- security microcontainer builder

The traditional container construction process requires a series of complex steps. Smith is a microcontainer construction tool that solves the problem of building consistency and security. You can easily build microcontainers through rpms, yum libraries, and even existing containers. For more information on building microcontainers, see the Microcontainer Manifesto.

Crashcart-- microcontainer debugging tool

If the simplified configuration of containers in the production environment leads to the lack of diagnostic tools, it is a great challenge for operation and maintenance. Although most diagnostics can be done on the primary node, diagnostics sometimes need to be done on the file system accessible to the container node. Crashcart is used in this scenario, which loads a set of data for the running container to locate the cause of the failure. To understand the principle of how crashcart locates unilateral loading data faults, please refer to Hardcore Container Debugging.

Railcar-- optional container Runtime

The Go language is not necessarily a * * choice for container runtime. Note: runtime is a component that is isolated through namespaces and cgroups. The Go language is still a very wise choice for container images and CLIS.) For ease of understanding, read the blog: Linux Namespaces And Go Don't Mix. Part of the code for Runc (runc is the default component of oci runtime) is written in C and called before the Go runtime starts. Although Go is a great language, there is a better choice for small components that require only light thread control and a large number of system calls. The Rust language can provide lightweight control similar to the C language, but memory is secure and avoids BUG and vulnerabilities of the class. For more information on the development of Railcar, please see Building a Container Runtime in Rust.
