Ansible v5 appears to rely on setfacl more than ansible 2.9 did when running tasks as a different unprivileged user than the one currently running ansible. Without setfacl installed we get errors like: Failed to set permissions on the temporary files Ansible needs to create when becoming an unprivileged user (rc: 1, err: chmod: invalid mode: ‘A+user:stack:rx:allow’ Try 'chmod --help' for more information.}). For information on working around this, see https://docs.ansible.com/ansible-core/2.12/user_guide/become.html#risks-of-becoming-an-unprivileged-user Installing setfacl makes the error go away as ansible get use setfacl instead of chown/chmod. Ubuntu, Debian, Fedora, CentOS, and OpenSUSE all appear to call the package 'acl'. We assume that openeuler and rocky inherit this package name. That means we only need to override the package name for Gentoo. Change-Id: I71736578dbd5e0683b18023e73ab44255eb6eb18 |

Using diskimage-builder to build devstack-gate nodes
In addition to being able to just download and consume images that are the same as what run devstack-gate, it's easy to make your own for local dev or testing - or just for fun.
Install diskimage-builder
Install the dependencies:
sudo apt-get install kpartx qemu-utils curl python-yaml debootstrapInstall diskimage-builder:
sudo -H pip install diskimage-builderBuild an image
Building an image is simple, we have a script!
bash tools/build-image.shSee the script for environment variables to set distribution, etc. By default it builds an ubuntu-minimal based image. You should be left with a .qcow2 image file of your selected distribution.
Infra uses the -minimal build type for building Ubuntu/CentOS/Fedora. For example: ubuntu-minimal.
It is a good idea to set TMP_DIR to somewhere with
plenty of space to avoid the disappointment of a full-disk mid-way
through the script run.
While testing, consider exporting DIB_OFFLINE=true, to skip updating the cache.
Mounting the image
If you would like to examine the contents of the image, you can mount it on a loopback device using qemu-nbd.
sudo apt-get install qemu-utils
sudo modprobe nbd max_part=16
sudo mkdir -p /tmp/newimage
sudo qemu-nbd -c /dev/nbd1 /path/to/devstack-gate-precise.qcow2
sudo mount /dev/nbd1p1 /tmp/newimageor use the scripts
sudo apt-get install qemu-utils
sudo modprobe nbd max_part=16
sudo tools/mount-image.sh devstack-gate-precise.qcow2
sudo tools/umount-image.shOther things
It's a qcow2 image, so you can do tons of things with it. You can upload it to glance, you can boot it using kvm, and you can even copy it to a cloud server, replace the contents of the server with it and kexec the new kernel.
