Emilua is an execution engine. As a runtime for your Lua programs

A generic C-powered & Lua-driven container runtime. Many container runtimes out there focus on specific containerization technologies such as Linux namespaces, but Emilua acts as a generic container runtime that supports different kernel technologies : Linux namespaces. FreeBSD jails. Many container runtimes (e.g. bubblewrap, nsjail) are CLI-driven and give little room for flexibility. The standard tool to automate CLI usage is BASH. However BASH cannot be used to restore flexibility here (it can only automate CLI arguments). BASH scripts are a poor match for the internal container setup phases, and that’s not usually supported. Even when BASH is supported for the setup phases (e.g. LXC pre-mount, and net-up scripts), that’s usually very restricted in scope given how inappropriate BASH is to drive the setup phases of a container. BASH scripts give you more worries to bring up a container, not less: Poor synchronization primitives to drive the complex setup required to use new Linux ... Read full article.
