This PR provides improved support for running crawler as non-root,
matching the user to the uid/gid of the crawl volume.
This fixes#502 initial regression from 0.12.4, where `chmod u+x` was
used instead of `chmod a+x` on the node binary files.
However, that was not enough to fully support equivalent signal handling
/ graceful shutdown as when running with the same user. To make the
running as different user path work the same way:
- need to switch to `gosu` instead of `su` (added in Brave 1.64.109
image)
- run all child processes as detached (redis-server, socat, wacz, etc..)
to avoid them automatically being killed via SIGINT/SIGTERM
- running detached is controlled via `DETACHED_CHILD_PROC=1` env
variable, set to 1 by default in the Dockerfile (to allow for overrides
just in case)
A test has been added which runs one of the tests with a non-root
`test-crawls` directory to test the different user path. The test
(saved-state.test.js) includes sending interrupt signals and graceful
shutdown and allows testing of those features for a non-root gosu
execution.
Also bumping crawler version to 1.0.1
* Run in Docker as User
This follows a similar pattern to pywb to run as the user that owns the
crawls directory.
bump version to 0.7.0-beta.6
Closes#170
