For instance:\n\n- The only way to use multiple images at once is through multi-stage builds, which,\n  though great, make it difficult to install multiple dependencies. Have a project that\n  needs to be built on CentOS and depends on devtoolset-7, Python, and Ruby in one\n  build stage? Tough luck; you'll have to pick one image and then install everything\n  else onto it manually.\n- It's a bit unintuitive to run an image directly using a temporary container. Want to\n  run the Alpine image just once? Try `docker run -t -i --rm alpine ash`. Ouch.\n- The new mount syntax makes bind mounts (which is what you'll almost always be using\n  for building binaries) painful: `--mount type=bind,source=xyz,destination=xyz`.\n- You can only depend on already-built images, not unbuilt Dockerfiles. This makes\n  creating multiple images harder than it needs to be.\n\n## What's wrong with rkt?\n\n- acbuild combines everything wrong with state machines and everything wrong with\n  declarative build formats into one.\n- AppC is dead, and rkt doesn't support OCI yet. Oh, as as a result of OCI,\n  acbuild is unmaintained.\n\n## What's wrong with Rootbox?\n\n[Rootbox](https://project-rootbox.github.io), IsolateKit's predecessor, was great, but\nit had a lot of problems:\n\n- I wrote it in Bash. Seemed like a good idea at the time, ended up being an epic\n  disaster.\n- There was no concept of proper dependency management, so creating new boxes required\n  running all of the factories it depended on...even if there was no need.\n- It was hard-coded to Alpine Linux and wasn't designed in a way to make it easily\n  extensible. Alpine is great for building static binaries, but you can't use it to\n  build other things like AppImages.\n\n## IsolateKit Highlights\n\n- Lightweight. GLib is the only runtime dependency, and Vala is the only built-time\n  dependency.\n- Built on top of systemd-nspawn.\n- Designed to make generating environments from source scripts insanely easy. IsolateKit\n  in its current state isn't really designed around using binary images.\n\n## Examples\n\n```bash\n# Create a new target that depends on the Alpine unit.\n$ ik target set test -a ik:alpine.rc\n# Run the new target.\n$ ik target run test\n# Run the new target, but also add the SDK unit.\n$ ik target run test -a ik:alpine/sdk.rc\n# Run the Alpine unit, but with no target.\n# This will discard any changes made (think docker run --rm).\n$ ik target run null -a ik:alpine.rc,alpine/sdk.rc\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frefi64%2Fisolatekit","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Frefi64%2Fisolatekit","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frefi64%2Fisolatekit/lists"}
