Configuration of PyCaosDB

The behavior of PyCaosDB is defined via a configuration that is provided using configuration files. PyCaosDB tries to read from the inifile specified in the environment variable PYCAOSDBINI or alternatively in ~/.pycaosdb.ini upon import. After that, the ini file pycaosdb.ini in the current working directory will be read additionally, if it exists.


The default configuration (that your are asked for your password when ever a connection is created can be changed by setting password_method:

  • with password_method=input password (and possibly user) will be queried on demand (default)
  • use the password manager pass by using pass as value, see also the ArchWiki entry. This also requires password_identifier which refers to the identifier within pass for the desired password.
  • install the python package keyring, to use the system keyring/wallet (macOS, GNOME, KDE, Windows). The password will be queried on first usage.
  • with password_method=plain (strongly discouraged)

# password using "pass" password manager

# using the system keyring/wallet (macOS, GNOME, KDE, Windows)

#discouraged: password in plain text

SSL Certificate

You can set the pass to the ssl certificate to be used:


Further Settings

debug=0 ensures that debug information is not printed to the terminal every time you interact with CaosDB which makes the experience much less verbose. Set it to 1 or 2 in case you want to help debugging (which I hope will not be necessary for this tutorial) or if you want to learn more about the internals of the protocol.

A complete list of options can be found in the pycaosdb.ini file in the examples folder of the source code.
