NAME¶
adt-virt-ssh - autopkgtest virtualisation server using SSH
SYNOPSYS¶
adt-virt-ssh [
options]
[-- setup script options ...]
DESCRIPTION¶
adt-virt-ssh provides an autopkgtest virtualisation server using SSH.
Normally
adt-virt-ssh will be invoked by
adt-run.
adt-virt-ssh
can use an already existing ssh target, or call a setup script to create/set up
a test bed and the ssh server.
WARNING! adt-virt-ssh will modify the target system by installing
packages and running arbitrary test code, so
you are responsible for
resetting the testbed youself especially without a setup script. So use
this with care.
REQUIREMENTS¶
adt-virt-ssh doesn't assume anything regarding the target host other than
that the given ssh connection (and networking) stay available all the time.
You can provide credententials on the command line for already working SSH
hosts or use a setup script to prepare the host for the connection (see
SETUP SCRIPT below for more information), for example to create a
forwarding rule to access an adb host over ssh or fire-up a cloud instance.
OPTIONS¶
- -h|--help
- Show the help message and exit
- -d|--debug
- Enable debugging output
- -H hostname | --hostname=hostname
- Connects and logs into the specified hostname or IP address
- -l user | --login=user
- Specifies the user to log in as on the remote machine.
- -i identity | --identity=identity
- Selects a file from which the identity (private key) for public key
authentication is read. Should usually be ~/.ssh/id_rsa, but you
might consider using a different key for tests.
- -P password | --password=password
- Specifies the sudo password on the remote host.
It can be the password in clear text or a file containing the password. This
password will be used to setup SUDO_ASKPASS in the case sudo requires a
password. The runner will check if the user has sudo access with and
without a password. If the check fails, the capability
"root-on-testbed" will not be available.
- -p port | --port=port
- ssh port to use to connect to the host
- -o options | --options=options
- Passed verbatim to ssh; see man ssh_config
- -s setup_script |
--setup-script=setup_script
- Setup script to prepare testbed and ssh connection (See SETUP
SCRIPT below for more information). File names will be searched in
both the current directory and in /usr/share/autopkgtest/ssh-setup/
so you do not need to give the full path for setup scripts shipped with
autopkgtest.
- -- [setup script arguments]
- All the remaining arguments following -- will be passed verbatim to
the setup script to configure the host.
CONFIGURATION FILES¶
If you use lots of options or hosts, you can put parts of, or the whole command
line into a text file, with one line per option. E. g. you can create a file
testhost.cfg with contents like
-Htest.example.com
-ltestuser
-Ps3kr1t
and then run
adt-run [...] --- adt-virt-ssh @testhost.cfg
The contents of the configuration file will be expanded in-place as if you would
have given its contents on the command line. Please ensure that you
don't
place spaces between short options and their values, they would become a
part of the argument value.
The behaviour of
adt-virt-ssh is as described by the AutomatedTesting
virtualisation regime specification.
NOTES¶
adt-run does not run
apt-get update at the start of a package
build, which can cause a build failure if you are using a development series
template. You will need to run
apt-get update in the template yourself
(e. g. using
--setup-commands).
SETUP SCRIPT¶
adt-virt-ssh accepts a setup script in argument to prepare the testbed
and the ssh connection. A setup script is an executable that gets called with
a command as first argument, and additional options for that command.
command: open¶
When called with "open", the script has to create a testbed (if
necessary), configure ssh, copy ssh key into it, configure sudo, etc.
It then returns the following information on standard output with the form
key=value, one line per pair. These mostly mirror the command line
options when not using a script.
Required fields:
- *
- login: User name
- *
- hostname: hostname or IP address
Optional fields:
- *
- identity: Path to the private key
- *
- password: sudo password for the user name to acquire root privileges. If
not given, and passwordless sudo does not work, the testbed will not have
root privileges.
- *
- port: SSH port on hostname, if different than 22
- *
- capabilities: extra testbed capabilities such as
"isolation-machine" or "revert", see
README.virtualisation-server.rst
- *
- options: passed verbatim to ssh, see man ssh_config
- *
- extraopts: passed verbatim to other commands; this allows extra state
(such as temporary directory names, VM identifiers, etc.) to be passed to
cleanup
command: cleanup¶
Called when closing the testbed; should revert/remove things installed in open
as much as possible if the testbed is not ephemeral. This gets called with all
the options that open got called with, plus
extraopts.
command: revert¶
If there is a way to reset the testbed to its pristine state (such as using VM
snapshots or rebuilding ephemeral testbeds), the script should put
"revert" (and if appropriate, "revert-full-system") into
the capabilities and implement this command. This can optionally output some
or all of the ssh config keys from open() to update the configuration, in case
the hostname/IP changes.
command: reboot¶
If the testbed can be rebooted with keeping state, the script should put
"reboot" into the capabilities and implement this command.
Included scripts¶
autopkgtest provides setup scripts for common types of testbeds in
/usr/share/autopkgtest/ssh-setup/. Please see the comments in these
scripts for how to use them. Also, please consider using
/usr/share/autopkgtest/ssh-setup/SKELETON as a basis for writing your
own.
EXAMPLES¶
Run the tests of the libpng source package on an existing
"mytesthost":
adt-run libpng --- ssh -H mytesthost -l joe -P /tmp/joe_password
Run the tests of a click package on an Ubuntu phone with an ssh connection over
ADB, using the setup script, with specifying an option to the setup script to
pick a particular serial ID:
adt-run ./ubuntu-calculator-app ./com.ubuntu.calculator_1.3.283_all.click \
--- ssh -s /usr/share/autopkgtest/ssh-setup/adb -- -s 0123456789abcdef
