Sending the Ctrl-Break signal to PowerShell <6 causes it to drop into
debug mode. Closing its output pipe at that point will block
indefinitely and prevent the process from being killed by Nomad.
See the upstream powershell issue for details:
https://github.com/PowerShell/PowerShell/issues/4254
This commit changes the force closing of the stdout/stderr file
descriptor from closing immediately to being closed after a grace
period. This allows the created process to close its own file and allows
copying of the data.
Fixes#2478#2474#1995#2294
The new client only handles agent and task service advertisement. Server
discovery is mostly unchanged.
The Nomad client agent now handles all Consul operations instead of the
executor handling task related operations. When upgrading from an
earlier version of Nomad existing executors will be told to deregister
from Consul so that the Nomad agent can re-register the task's services
and checks.
Drivers - other than qemu - now support an Exec method for executing
abritrary commands in a task's environment. This is used to implement
script checks.
Interfaces are used extensively to avoid interacting with Consul in
tests that don't assert any Consul related behavior.
This PR:
* Uses Go 1.8 executable lookup
* Stores any err message from stats init method
* Allows overriding of Cpu Compute for hosts where it can't be detected
This PR fixes our vet script and fixes all the missed vet changes.
It also fixes pointers being printed in `nomad stop <job>` and `nomad
node-status <node>`.
- Simplify map length check in Linux Executor
- Added a `chroot_env` test for config parser
- Moved `ChrootEnv` field from ExecutorCommand to ExecutorContext
- Added a test for `chroot_env` functionality
- Same format as used by the internal chroot mapping
- Map: source_path -> dest_path
- Example HCL:
client {
chroot_env {
"/etc" = "/etc"
"/lib" = "/lib"
"/opt/projects/foo/bin" = "/usr/bin"
}
}
