The key generated from this command is used for gossip encrpytion, which utilizes AES GCM encryption. Using a key size of 16-bytes enables AES-128 while a key size of 32 bytes enables AES-256.
The underlying memberlist library supports the larger key size, and is ultimatley preferable from a security standpoint. Consul also uses 32 bytes by default: 1a14b94441
Since CPU resources are usually a soft limit it is desirable to allow
setting it as low as possible to allow tasks to run only in "idle" time.
Setting it to 0 is still not allowed to avoid potential unintentional
side effects with allowing a zero value. While there may not be any side
effects this commit attempts to minimize risk by avoiding the issue.
This does *not* change the defaults.
Volume requests can be either CSI or host volumes, so when displaying the CSI
volume info for `nomad node status -verbose` we need to filter out the host
volumes.
The initial implementation of global job stop for MRD looped over all the
regions in the CLI for expedience. This changeset includes the OSS parts of
moving this into the RPC layer so that API consumers don't have to implement
this logic themselves.
This PR adds initial support for running Consul Connect Ingress Gateways (CIGs) in Nomad. These gateways are declared as part of a task group level service definition within the connect stanza.
```hcl
service {
connect {
gateway {
proxy {
// envoy proxy configuration
}
ingress {
// ingress-gateway configuration entry
}
}
}
}
```
A gateway can be run in `bridge` or `host` networking mode, with the caveat that host networking necessitates manually specifying the Envoy admin listener (which cannot be disabled) via the service port value.
Currently Envoy is the only supported gateway implementation in Consul, and Nomad only supports running Envoy as a gateway using the docker driver.
Aims to address #8294 and tangentially #8647
The `regionForJob` function in the HTTP job endpoint overrides the region for
multiregion jobs to `global`, which is used as a sentinel value in the
server's job endpoint to avoid re-registration loops. This changeset removes
an extraneous check that results in errors in the web UI and makes
round-tripping through the HTTP API cumbersome for all consumers.
* command/debug: print interval data so the operator knows its waiting
* command/debug: use the Consul/Vault env for queries
* command/debug: capture the operator endpoints
* command/debug: capture API errors in the archive bundle
