This PR updates the version of redis used in our examples from 3.2 to 7.
The old version is very not supported anymore, and we should be setting
a good example by using a supported version.
The long-form example job is now fixed so that the service stanza uses
nomad as the service discovery provider, and so now the job runs without
a requirement of having Consul running and configured.
Many of our scripts have a non-portable interpreter line for bash and
use bash-specific variables like `BASH_SOURCE`. Update the interpreter
line to be portable between various Linuxes and macOS without
complaint from posix shell users.
* Use unix:// prefix for CSI_ENDPOINT variable by default
* Some plugins have strict validation over the format of the
`CSI_ENDPOINT` variable, and unfortunately not all plugins
agree. Allow the user to override the `CSI_ENDPOINT` to workaround
those cases.
* Update all demos and tests with CSI_ENDPOINT
This changeset expands on the existing demonstration we had for Ceph by
showing volume creation. It includes a demo setup for Ceph on Vagrant so that
you don't need a whole Ceph cluster to try it out.
A demo for the CSI hostpath plugin, used primarily for development
purposes. This reproduction has been used for testing during our CSI
implementation work, and this changeset makes that public.
Examples for HTTP based task-group service healthchecks are
covered by the `countdash` demo, but gRPC checks currently
have no runnable examples.
This PR adds a trivial gRPC enabled application that provides
a Service implementing the standard gRPC healthcheck interface.
We use the education team's "countdash" demo in many places
to showcase Nomad's Consul Connect integration. This change
adds a Dockerfile for each of `counter-dashboard` and
`counter-api` that can be used to build artifacts to publish
to Nomad's Docker Hub organization.
The recent "0.0.3" release of the `countdash` demo includes
changes we want in order to demo task group service checks.
The provision shell script tries to install libssl1.1 package as dependency of ca-certificates package.
The installing of libssl requires to restart some services, and it asks for confirmation of this.
But there are no interactive session at this stage, so Vagrant provisioning just hungs.
This commit add a `libraries/restart-without-asking boolean true` setting before installing libssl,
so it doesn't ask confirmation anymore and the provisioning works again.
