2021-04-02Implement the runsc verity-prepare command.Rahat Mahmood
Implement a new runsc command to set up a sandbox with verityfs and run the measure tool. This is loosely forked from the do command, and currently requires the caller to provide the measure tool binary. PiperOrigin-RevId: 366553769
2021-03-23setgid directory support in goferfsKevin Krakauer
Also adds support for clearing the setuid bit when appropriate (writing, truncating, changing size, changing UID, or changing GID). VFS2 only. PiperOrigin-RevId: 364661835
2021-03-06[op] Replace syscall package usage with golang.org/x/sys/unix in runsc/.Ayush Ranjan
The syscall package has been deprecated in favor of golang.org/x/sys. Note that syscall is still used in some places because the following don't seem to have an equivalent in unix package: - syscall.SysProcIDMap - syscall.Credential Updates #214 PiperOrigin-RevId: 361381490
2020-12-03Surface usage message for `runsc do`.Dean Deng
c.Usage() only returns a string; f.Usage() will print the usage message. PiperOrigin-RevId: 345500123
2020-10-15`runsc do` fallback to internal network on failureFabricio Voznika
In case setting up network fails, log a warning and fallback to internal network. Closes #4498 PiperOrigin-RevId: 337442632

2020-04-27runsc: extend do network cleanupMichael Pratt
Previously we unconditionally failed to cleanup the networking files (hostname, resolve.conf, hosts), and failed to cleanup the netns, etc on partial setup failure. We can drop the iptables commands from cleanup, as the routes automatically go away when the device is deleted. Those commands were failing previously. Forward signals to the container, allowing it to exit normally when a signal is received, and then for runsc to run the cleanup. This doesn't cover cleanup when runsc is signalled before the container start, it covers the most common case. Fixes #2539 Fixes #2540

2019-06-18Kill sandbox process when 'runsc do' exitsFabricio Voznika
PiperOrigin-RevId: 253882115
2019-06-18Add Container/Sandbox args struct for creationFabricio Voznika
There were 3 string arguments that could be easily misplaced and it makes it easier to add new arguments, especially for Container that has dozens of callers. PiperOrigin-RevId: 253872074

2019-06-12Allow 'runsc do' to run without rootFabricio Voznika
'--rootless' flag lets a non-root user execute 'runsc do'. The drawback is that the sandbox and gofer processes will run as root inside a user namespace that is mapped to the caller's user, intead of nobody. And network is defaulted to '--network=host' inside the root network namespace. On the bright side, it's very convenient for testing: runsc --rootless do ls runsc --rootless do curl www.google.com PiperOrigin-RevId: 252840970
2019-05-30runsc/do: don't specify the read-only flag for the root mountAndrei Vagin
The root mount is an overlay mount. PiperOrigin-RevId: 250429317
2019-05-30runsc/do: allow to run commands in a host network namespaceAndrei Vagin
PiperOrigin-RevId: 250329795
2019-05-23runsc/do: do a proper cleanup if a command failed due to internal errorsAndrei Vagin
Fatalf calls os.Exit and a process exits without calling defer callbacks. Should we do this for other runsc commands? PiperOrigin-RevId: 249776310 Change-Id: If9d8b54d0ae37db443895906eb33bd9e9b600cc9
2019-05-03Fix runsc restore to be compatible with docker start --checkpoint ...Andrei Vagin

2019-05-02Add [simple] network support to 'runsc do'Fabricio Voznika
Sandbox always runsc with IP 192.168.10.2 and the peer network adds 1 to the address (192.168.10.3). Sandbox IP can be changed using --ip flag. Here a few examples: sudo runsc do curl www.google.com sudo runsc do --ip=10.10.10.2 bash -c "echo 123 | netcat -l -p 8080" PiperOrigin-RevId: 246421277 Change-Id: I7b3dce4af46a57300350dab41cb27e04e4b6e9da

2019-04-11Add 'runsc do' commandFabricio Voznika
It provides an easy way to run commands to quickly test gVisor. By default it maps the host root as the container root with a writable overlay on top (so the host root is not modified). Example: sudo runsc do ls -lh --color sudo runsc do ~/src/test/my-test.sh PiperOrigin-RevId: 243178711 Change-Id: I05f3d6ce253fe4b5f1362f4a07b5387f6ddb5dd9
