This commit does a few things:
1. Make the hostname update idempotent with `grep -w`
2. Add the given hostname to `/etc/hosts` as recommended by the docs
3. Add missing tests
This commit updates the procedure for configuring arch networks to occur
in a single command. Previously, each network was configured
independently. If, for some reason, one of the networks destroyed the
SSH connection, the box would be irrecoverable. This commit does not
alleviate that behavior, but attempts to mitigate it by running all
network-related configuration commands in a single communicator (SSH)
session.
The new procedure looks like this:
1. Upload a temp file to /tmp/vagrant-network-id... for each interface
on the guest.
2. Compile a commands array (of bash) to execute after all network
configurations have been uploaded.
3. Concatenate all the commands together in a single communicator
session.
This was tested against `terrywant/archlinux` using the following Vagrantfile:
```ruby
Vagrant.configure(2) do |config|
config.vm.box = "terrywang/archlinux"
config.vm.hostname = "banana-ramama.example.com"
config.vm.network "private_network", type: "dhcp"
config.vm.network "private_network", ip: "33.33.33.10"
config.vm.provision "file", source: "Vagrantfile", destination: "/tmp/vf"
config.vm.provision "shell", inline: "echo hi"
end
```
This commit updates the procedure for changing the hostname on arch
guests to occur in a single command. Previously, setting the hostname
and adding the value of the hostname to the /etc/hosts file was done in
two different uploads. This reduces the cycle to a single upload, making
provisioning a bit faster.
Additionally, this changes the behavior of the /etc/hosts file to:
1. Not remove localhost as an alias of 127.0.0.1
2. Prepend our custom hostname before localhost
The resulting /etc/hosts file will look something like:
127.0.0.1 my-host.example.com my-host
127.0.0.1 localhost.mydomain localhost
Tested against `terrywang/archlinux` using the following Vagrantfile:
```ruby
Vagrant.configure(2) do |config|
config.vm.box = "terrywang/archlinux"
config.vm.hostname = "banana-ramama.example.com"
config.vm.network "private_network", type: "dhcp"
config.vm.network "private_network", ip: "33.33.33.10"
config.vm.provision "file", source: "Vagrantfile", destination: "/tmp/vf"
config.vm.provision "shell", inline: "echo hi"
end
```
With this change, the presence of Ansible configuration files (like
playbook file, inventory path, galaxy role file, etc.) is no longer
performed by the `config` classes, but by the `provisioner` classes
(at the beginning of the provision command).
This change fixes several issues:
- Resolve#6984 as `provision` method are only executed when remote
(ssh) communication with the guest machine is possible.
- Resolve#6763 in a better way than 4e451c6 initially did.
- Improve the general provisioner speed since the `config` checks are
actually triggered by many vagrant actions (e.g. `destroy`,...), and
can also be triggered multiple times during a vagrant run (e.g. on
callback request made by the machine provider).
Unlike the former `config`-based checks, the provision action won't
collect all the invalid options, but only report the first invalid
option found and abort the execution.
Some unit tests were not implemented yet to save my scarce "open source
contribution time" for other important issues, but they should be done
at last via GH-6633.
Vagrant's environment (which includes the known list of boxes and
versions) is established at the start of the Vagrant run. This means
that box downloads which occur during the run are not contained in the
set until the next run. This causes duplicate box downloads to raise an
error in multi-machine Vagrantfiles.
This commit fixes that issue by pre-processing the machines by provider
and version, creating a unique set of boxes to update.
Fixes GH-6042
This adds a new core command, `docker-exec`, which allows the user to
exec into an already-running container.

This commit changes the way ports are aggregated in the Docker provider.
Previously ports were aggregated by their "number", but that is not a
truly unique representation. Instead, the protocol is now taken into
account when generating the port map.
Fixes GH-5527
This adds two new SSH configuration options:
- `keys_only`
- `paranoid`
These values were previously hard-coded, but can now be user-specified.
Fixes GH-4275
Changes:
- Add "config" unit tests for `ansible_local` (guest)
- Share some "config" examples between both ansible provisioners
- Move `config_host.rb` specific examples to `config/host.rb`
- Add a requirement to "../helpers" in `config/guest.rb` in order to be
able to run the related unit tests
References:
- This is the first part of GH-6633 resolution
- This change is a handy prerequisite for GH-6570
Not addressed yet:
- FIXME (guest.rb): Some test-double stubs are currently not working as
expected, and the related checks are commented out for the moment
(no idea why, but this is not urgent to be fixed because of GH-7335
rejection. See also GH-6984)
- FIXME (shared.rb): The guest-based config should actually NOT return
an error when the extra_vars file cannot be found, but only display a
a warning (similarly to the changes done for GH-6763, see 4e451c6)
This fixes a fairly large tempfile leak. Vagrant uses a template
renderer to write network configuration files locally to disk. Then,
that temporarily file is uploaded to the remote host and moved into
place. Since Vagrant is such a short-lived process, GC never came along
and cleaned up those tempfiles, resulting in many temporary files being
created through regular Vagrant usage.
The Util::Tempfile class uses a block to ensure the temporary file is
deleted when the block finishes. This API required small tweaks to the
usage, but provides more safety to ensure the files are deleted.
This commit basically grepped the code base for all uses of Dir.mktmpdir
and Tempfile.new/open and ensures the value is unique within the
code base and also prefixed with `vagrant-`.
Previously, most invocations of these commands simply used "vagrant",
thus making them indistinguishable when trying to identify leaks.
Previously, there was no one gesture that would start a VM if it was not
running and run the appropriate provisioners regardless of its original
state. `vagrant up` did nothing if the VM was running, while
`vagrant provision` did nothing if the VM was not running.
Change the semantics of `vagrant up`, via the start actions of the providers,
to go through the provisioning logic even if the VM is already running.
The semantics of `run: "once"` vs `run: "always"` are respected.
Tested with the VirtualBox provider but not the others.
Resolves#4421
This commit separates the scratch and output directory creation from the
main package middleware into its own PackageSetupFolders middleware.
Additionally, the validation that ensures an output file does not exist
is moved into a validation function that can be shared across multiple
methods.
This refactor permits a pre-flight check to ensure box packaging would
be successful before actually stopping the VM.
Fixes GH-7351
Vagrant was not behaving correctly in configurations where there was
a static IP on a VirtualBox `intnet` interface and a DHCP `:hostonly`
interface configured.
Since `machine_ip` attempted to get static addresses `||` dynamic
addresses, it would simply use the static machine address and
continue.
This commit corrects this behaviour by collecting all static and
dynamic addresses into the `machine_ip` array instead of just one or
the other.
The result of this is a correctly generated `/etc/exports` on the
host machine, allowing NFS mounts to work correctly in this type of
environment.
