Move the words being defined in the /docs/internal/architecture page to be
small headers so that they can be linked to with anchors from Learn guides and
other documentation location.
The `dist/` directory is unmaintained and gets out of sync with the Linux
packages that we distribute and the documentation found in the Learn
Guides. We even have upstart files for a distro that is out of support!
Remove this directory so that users are not confused.
While working on voxpupuli/puppet-nomad/pull/50 we observed that the released version of this file and the file in this repo are not in sync. This PR brings the systemd service file in sync with what is currently packaged into the rpm and deb packages as released in the HashiCorp repositories. I am not sure how/where to update the [deployment guide](https://learn.hashicorp.com/tutorials/nomad/production-deployment-guide-vm-with-consul#configure-systemd)
The error output being checked depends on the linux caps supported
by the particular operating system. Fix these test cases to just
check that an error did occur.
Update docs for allow_caps, cap_add, cap_drop in exec/java/docker driver
pages. Also update upgrade guide with guidance on new default linux
capabilities for exec and java drivers.
This changeset does not introduce any functional change for the
docker driver, but rather cleans up the implementation around
computing configured capabilities by re-using code written for
the exec/java task drivers.
This PR enables setting allow_caps on the exec driver
plugin configuration, as well as cap_add and cap_drop in
exec task configuration. These options replicate the
functionality already present in the docker task driver.
Important: this change also reduces the default set of
capabilities enabled by the exec driver to match the
default set enabled by the docker driver. Until v1.0.5
the exec task driver would enable all capabilities supported
by the operating system. v1.0.5 removed NET_RAW from that
list of default capabilities, but left may others which
could potentially also be leveraged by compromised tasks.
Important: the "root" user is still special cased when
used with the exec driver. Older versions of Nomad enabled
enabled all capabilities supported by the operating system
for tasks set with the root user. To maintain compatibility
with existing clusters we continue supporting this "feature",
however we maintain support for the legacy set of capabilities
rather than enabling all capabilities now supported on modern
operating systems.
This closes#10513, thanks to @bastelfreak for the report.
GET /status/leader returns an IPv6 host with square brackets
around the IP address as expected, but the rpcAddr property
on the agent model does not.
This fixes rpcAddr, updates the Mirage /status/leader mock
to properly format an IPv6 host, and changes the agent
factory to sometimes produce IPv6 addresses.
I added a formatHost utility function to centralise the
conditional square bracket-wrapping that would have
otherwise been further scattered around.
