Interpreter to specify the virtualenv for those. you will normally have a workon command, or use a specific path to the Python Page, and then click the green "Reload" button to restart the site using it.įor always-on and scheduled tasks, change the command used to run them to pick up the new virtualenv If your virtualenv is used in a website, change the virtualenv setting on the "Web" Once that's done, you can start using it. Ensure your new virtualenv is activated, then: pip install -r /tmp/requirements.txt # or path to your existing requirements.txt Or, for a plain virtualenv: virtualenv -python =pythonX.Y /home/myusername/path/to/new-virtualenv Virtualenvwrapper, create it like this: mkvirtualenv -python =pythonX.Y my-new-virtualenv-name Only need the first two digits from the version number, eg. Once you've determined the Python version, create the new virtualenv - this will The numbers after the second "."Īre not important here for example, if you got 3.9.13, any image that supported 3.9 would be OK. Got above will be a full three-part version, for example 3.9.13. Is available in the new system image by looking at the table at the bottom of the That the version that you identified when gathering data about your old virtualenv The first step is to identify the version of Python that you are going to use check We recommend that you create a new virtualenv with a different name, just inĬase something goes wrong in its creation. Now you have saved the information you need about the virtualenv, so you canĬhange the system image. Next, check which Python version you are using: python -versionįinally, deactivate the virtualenv deactivate If you've already got a file like that, you can skip this, but otherwise: pip freeze > /tmp/requirements.txt Next, generate a requirements.txt file to record what packages you're using. Or, if you're using a plain one: source /home/myusername/path/to/virtualenv/bin/activate If you're using virtualenvwrapper: workon my-virtualenv-name 1) Before the system image change ¶įirstly, activate the virtualenv. Virtualenv and virtualenvwrapper make sure that you use the appropriate onesįor the kind of virtualenv you're using. The instructions below contain instructions for people who use plain Then, after you haveĬhanged it, you will be able to build a new one using that information. Will need to gather information about the virtualenv. There are two steps to this process firstly, before you change the image, you Everything is lost, except the backup files are available on a Repository in the disaster site or in the Capacity Tier of a Scale-out Backup Repository.Imagine that not even a configuration backup is available. Likely to need to rebuild your virtualenvs. Imagine a situation (a disaster), where the virtual infrastructure needs to be restored from scratch. If you are doing a system image upgrade, you are
