dew VS firejail

I've built dew for this. It "knows" about many of those apps (and where to get a container from). https://github.com/efrecon/dew. Adding a term app is usually just a matter of crafting an .env file with the necessary settings.

I have written dew (https://github.com/efrecon/dew) for more or less the same purpose. I hardly keep any binary (and dependency) in my installation, they are all inside containers that I can easily dispose of at any time. The default in dew is to run them as your user. At the command prompt, instead of running, for example, kubectl xxx, I run dew kubectl xxx. It's a bit slower but provides an increased level of security.

In the past few weeks, I have spent some time and released dew [0]. It helps encapsulating this kind of setups in configuration and minimising typing. dew is still evolving, but it has served me well.

bubblewrap is designed as a low-level too. There is nothing quick and dirty about it. It disallows everything by default and you have to be explicit about what you want to share with the host. If your application needs complex permissions/resources, then you will need to have a complex bubblewrap command line.

Once you have figured out which permissions/resources you need for a given program, you can wrap the command line invocation in a shell script.

If you want other people to do the work of defining permissions/resources, then have a look at firejail: https://github.com/netblue30/firejail

Firejail is cool: https://github.com/netblue30/firejail

Linux namespaces/cgroups but nowhere near as heavy as Docker.

I use it when I want to limit the memory of a Python script:

```

Firejail can also be a useful option, though no good if you're on Mac https://firejail.wordpress.com/

Uses the same Linux primitives as docker etc, but can be a bit more ergonomic for this use case

Firejail, Flatpak (which uses Bubblewrap under the hood), and Snap (which uses AppArmor) all use the same underlying technology: Linux namespaces.

This question comes up a lot, and has been answered here: https://github.com/netblue30/firejail/wiki/Frequently-Asked-...

TL;DR: Firejail has much more comprehensive features than Flatpak (Bubblewrap). Firejail also has more comprehensive network support, support for AppArmor and SELinux, and easier seccomp filtering.

Compared to Snap (which uses AppArmor), Firejail is compatible with AppArmor and again goes above and beyond with a lot of additional features.

Wonderful little tool, too bad you must chain various exec calling tools to get cgroups (a bit akin to `ionice ... nice ... cmd`) and Linux users namespaces can't allow UNIX sockets while preventing network access (I think?).

Migrated from Firejail when its complexity annoyed me too much and I hit https://github.com/netblue30/firejail/issues/3001 (Firejail doesn't like parens or brackets in --put/--get parameters) to a badly NIH version using bwrap and bash to have "profiles":

Firejail does this. The profile database is the two "profile" directories in https://github.com/netblue30/firejail/tree/master/etc

What do you mean by a Firefox container? Do you mean FireJail?
