Newton user guide for openstack newton mentions the command show for a stack. Example: openstack stack show <stack_name>.
However, latest docs stein don't mention anything about this command. How can I show stack info in latest openstack/openstackclient release (stein at the moment of writing this question)?
make sure you have not outdated version of python-openstackclient
just install it with pip in venv and then install python-heatclient from pip as well
That same functionality is still there. Check out https://docs.openstack.org/python-heatclient/stein/cli/stack.html
If the command is missing in your environment, then you probably just need to install python-heatclient. It is not available by default with the unified openstack client.

I can see the following in my pip list but when I try to add a Snowflake connection via the GUI, Snowflake is not an option from the dropdown.
apache-airflow-providers-snowflake 2.1.0
snowflake-connector-python 2.5.1
snowflake-sqlalchemy 1.2.3
Am I missing something?
I have had this issue with MWAA recently.
I find that if I select AWS in the drop down and provide the correct snowflake host name etc it works though.
I run into the same issue using the official helm chart 1.3.0.
But finally I was able to make Snowflake connection visible by doing the following steps:
I uninstalled the apache-airflow-providers-google. Not sure whether this is important, but I like to mention it here. I did this, because I got some warnings.
Because with SQLAlchemy 1.4 some breaking changes were introduced, I made sure that version 1.3.24 gets installed. Based on that I choosed the fitting version for snowflake stuff.
So this is my requirements.txt for my custom Airflow container:
apache-airflow-providers-snowflake==2.3.0
pyarrow==5.0.0
snowflake-connector-python==2.5.1
snowflake-sqlalchemy==1.2.5
SQLAlchemy==1.3.24
This is my Dockerfile:
FROM apache/airflow:2.2.1-python3.8
## adding missing python packages
USER airflow
COPY requirements.txt .
RUN pip uninstall apache-airflow-providers-google -y \
&& pip install -r requirements.txt
I had the same issue where my pip freeze showed the apache-airflow-providers-snowflake yet I did not have the provider in the UI. I had to add the line apache-airflow-providers-snowflake to my requirements.txt file and then restart. Then I was able to see the Snowflake provider and connector in the UI.
I have a code snippet which will not work for Kilo version. I know the Openstack version, now I'm willing to know step/s to fetch the neutron version.
3.18 is the version of the openstack command line client, not the version of OpenStack.
There are several possible Neutron versions in Stein, all starting with 14. To obtain the precise version, either check the Python code or run neutron-db-manage version --verbose on a controller (see the documentation for information about this command).
There is no API that gives you the version of the deployed software. You obtain the API version by sending an HTTP GET to the bare Neutron endpoint, e.g. curl http://example.com:9696.
While I can't promise anything (it may be hard to find a Kilo installation for checking), feel free to publish your code here, stating what exactly works and doesn't work in which version.
I have deployed a basic openstack using devstack. now I want to install additional component like designate or magnum. What is the way to do that?
I would try the Magnum installation guide. It gives you two options: Install using apt/yum/zypper packages, or install using pip.
You need to ensure you install the version that matches your Devstack version. E.g. if your Devstack is Ussuri, use Ussuri instructions.
Another possibility might be amending local.conf and rerun stack.sh. I am not sure if this breaks already installed software, though.
The safest solution is to add the enable_plugin directives for Magnum to local.conf before you deploy the cloud.
Very nooby question, but I'm trying to install Atom text editor on Raspbian Stretch. Is it possible? I've heard because it runs on Electron, it's quite slow for Raspbian. I keep getting an error saying:
E: Unable to locate package atom
I'm following the official instructions for Debian. How can I fix this?
As of today you can't install the official package provided for Debian for its mismatching the hardware platform. Provided binary is for running on x86 hardware, but RPi doesn't come with an Intel/AMD processor, but ARM. So, you most probably need to build it from source yourself.
Primer
So, if you really want to build this from source, you should be aware of the waste of disk space caused by the IMHO poorly implemented build tool which is downloading tons of deps and copying and transpiling code around so you'll end up with 2GB+ of files with 80% accounting to dependencies, only. Since my RPi works with 8GB smartcard, only, I couldn't ever meet the need for disk space even though I was bleeding out Linux by manually removing docs, manpages, locales, ton's of outdated and mostly unused apps etc. The build also requires a whole build tooling chain, tons of dev packages for libraries, so there is a limit to milk the system ... 8GB disk drive simply isn't enough for this.
Eventually I tried moving all the files to a USB pen drive. But that drive must be formatted using a filesystem capable of symlinking. So you can't use vfat or FAT32. I didn't succeed to get a 16GB stick formatted with either version of extfs. The mkfs always ended up in a deadlock on trying to write its superblocks. Astonishingly, I couldn't even kill the mkfs with -KILL, but unplugging the drive did help in that case.
So, as a conclusion: here is a short list of steps I passed in expectation to get this working, but in the end I didn't finish due to the memory issues above. And frankly, I stopped caring ... I'd rather work with nano/vi in a terminal than using this ridiculous lego-like built software. I guess, atom is today's version of emacs with regards to the latter's acronym. Maybe you succeed with this, but I won't ...
Build from Source
Inspired by https://discuss.atom.io/t/atom-on-the-raspberry-pi/33332
Install toolchain for building native stuff
sudo apt-get install build-essential git libgnome-keyring-dev fakeroot gconf2 gconf-service libgtk2.0-0 libudev1 libgcrypt20 python rpm libsecret-1-dev xorg-dev
This set of tools was sufficient to build core files without error. Since I didn't start with a fresh installation of Raspbian there might have been some tool I have been using before, so maybe in your case there are more tools to be installed here. Look out for error messages in early stage of building and try to see if some library or header file isn't found. This mostly indicates lack of some package with name ending in -dev to be installed, too. Start by searching for the package using apt search <name-of-mentioned-library> and look for a package combining the missing library's name with suffix -dev. Then install it the usual way by invoking sudo apt-get install <package-name>.
Install up-to-date nodejs
Raspbian Stretch comes with support for NodeJS 8.11 which is basically okay. Install it and its package manager npm using this command:
sudo apt-get install node-js npm
Check installed versions with
node -v
npm -v
This should display 8.x.x on behalf of NodeJs. Use n afterwards if you want to step up:
sudo npm i -g n
sudo n lts
This will switch NodeJS to latest LTS release, which is 10.x as of now. Upgrading NodeJS is optional, but feel advised to always use latest version of npm:
sudo npm i -g npm
Check if upgrades succeeded:
node -v
npm -v
Adjust configuration of npm and install some essential dep:
sudo npm config set -g python /usr/bin/python2
sudo npm i -g node-gyp
Build Atom
Get the source. One option is to pull latest code from its repository:
git clone https://github.com/atom/atom.git
This is creating subfolder atom containing all source files. You might want to download sources of a recent release instead. But this tutorial was made with the sources fetched from Github. So make sure there is subfolder called atom containing sources similar to the ones fetched above.
It's time to start the beast:
cd atom
./script/build
This process will take a while. And it is the culprit that never finished on success in my case due to eating up all disk space over and over again.
Whenever the script fails on error, try to analyze the error, find the cause, fix it, then start the script by repeating the last command above again. If you don't remove any file in subfolder atom in between, the build script keeps passing steps of building atom it has passed successfully before.
Install atom
According to the original tutorial linked before the script should finish on success eventually. Then it's time to install with:
./script/grunt install
I guess this is causing atom to be available as a command from CLI. So, try it out. If everything looks fine you are finally ready to remove the waste of files in subfolder atom.
Feel free to report if this was working in your case.
From what I recall Atom runs 64-bit architecture; need the latest raspberry Pi.
run the following
wget https://atom.io/download/deb && dpkg -i deb
I have deployed graphite with nginx some time ago, with chef, but didn't froze versions to be installed. Thus now, trying to install with the same recipe i get errors because of missing something related to versions.
I need to find what version of Graphite I have installed on my other CentOS machines, to be able to figure out how to repair recipe.
Thank you.
Gabriel
If you have web access to the Graphite installation, you can also see the currently running version under the /version/ path.
I had the same issue. I solved it running a pip list, which displays every package you installed with pip. You can also run pip show graphite-web or pip show whisper to get more specific information.
