Also I don&#8217;t care if an image can never be downloaded. Possible solutions would be to track state and have a failed counter to know when to just give up forever on a set.<\/li>\n<li>Send out an email on each successful database update.<\/li>\n<\/ul>\n<h2>Computer, resume program<\/h2>\n<p>I have rebooted since I last played around with faasd and thus the instance need to be started again.<\/p>\n<p>P.S.

This is not ideal. Really you would first do most of your development locally and only deploy as OpenFaaS once you have a good chunk working.<\/p>\n<p>To help me in this I created a file called indev.py that I use to develop\/explore code locally. indev stands for In Development and is a term I have used for a good 20 years for this kind of temporary \/ boot strap code (when not using TDD).<\/p>\n<pre><code class=\"language-python\">from legodb.handler import handle\nfrom pprint import pprint\n\nclass Event:\n    def __init__(self):\n        self.body = None\n        self.headers = None\n        self.method = 'GET'\n        self.query = None\n        self.path = '\/legosets'\n\nclass Context:\n    def __init__(self):\n        self.hostname = 'localhost'\n\nif __name__ == &quot;__main__&quot;:\n    event = Event()\n    context = Context()\n    response = handle(event, context)\n    print(f'{event.path}')\n    pprint(response)\n    print('')\n<\/code><\/pre>\n<p>I will need the secrets locally so I have created the 3 secrets required at: \/var\/openfaas\/secrets\/<\/p>\n<pre><code class=\"language-bash\">$ sudo mkdir -p \/var\/openfaas\/secrets\/\n$ sudo chown -R andre:staff \/var\/openfaas\n# Then created the files (I actually copied this directly from my faasd instance\ndatabase-host  database-password  database-user\n<\/code><\/pre>\n<h2>Shiny object distraction<\/h2>\n<p>At first I was going to use alembic to manage database migrations from SQLAlchemy but I ran into import issues that was just eating up to much of my time. So I will revisit using alembic another time.<\/p>\n<p><strong>Learning action point:<\/strong> Importing modules and files in Python has always been a bit of black magic to me. I need to spend some time to really understand how the import process works.<\/p>\n<p>Initially I was just going to store the image data as blob in the database, but this is never a good idea and even this little learning\/toy project it just wouldn&#8217;t feel correct. So after a bit of googling it seemed that one option would be to use SQLAlchemy-ImageAttach. But this also turned out to be more of time sinkhole than me actually learning the bits I wanted to learn about.<\/p>\n<p>So instead I will just have a column in the table to keep reference to where the image lives on disk after it has been downloaded.
