Extracting Public IPs from an Azure Tenant

The below one-liner allows you to extract all Public IPs (PIPs) assigned in your Azure tenant. Please note that this only covers PIPs and not address prefixes and other resources. You can easily modify the command to output other resources though.

# Output to console
Get-AzSubscription | ForEach-Object {Set-AzContext -Subscription $_.Name *>$null; Get-AzPublicIpAddress} | Where-Object {$_.IpAddress -ne 'Not Assigned'} | Select-Object -Property Name,PublicIpAllocationMethod,ipAddress,ProvisioningState,Location,ResourceGroupName,Id

and

# Write to CSV
Get-AzSubscription | ForEach-Object {Set-AzContext -Subscription $_.Name *>$null; Get-AzPublicIpAddress} | Where-Object {$_.IpAddress -ne 'Not Assigned'} | Select-Object -Property Name,PublicIpAllocationMethod,ipAddress,ProvisioningState,Location,ResourceGroupName,Id  | Export-Csv -Path .\pips.txt

Setting up JuyterHub for AD (or LDAP) Authentication

This is reasonably straight forward - you might get caught with an issue with the following though

c.LDAPAuthenticator.bind_dn_template

Here is the config

c.LDAPAuthenticator.lookup_dn_search_user = 'service_account'
    c.LDAPAuthenticator.lookup_dn_search_password = 'password'
    c.JupyterHub.authenticator_class = 'ldapauthenticator.LDAPAuthenticator'
    c.LDAPAuthenticator.server_address = 'ldap://server'
    c.LDAPAuthenticator.bind_dn_template = 'domain\{username}'
    c.LDAPAuthenticator.lookup_dn = False
    c.LDAPAuthenticator.user_search_base = 'OU=Corporate Services,OU=Users,OU=Agencies,DC=domain,DC=sub,DC=tld'
    c.LDAPAuthenticator.user_attribute = 'sAMAccountName'
    c.LDAPAuthenticator.allowed_groups = []
    c.Spawner.default_url = '/lab'
    c.Spawner.notebook_dir = '~'
    c.JupyterHub.spawner_class = 'systemdspawner.SystemdSpawner'
    c.SystemdSpawner.default_shell = '/usr/bin/zsh'
    c.SystemdSpawner.username_template = 'jupyter-{username}'
    c.SystemdSpawner.unit_name_template = 'jupyter-singleuser'
    c.SystemdSpawner.disable_user_sudo = False
    c.SystemdSpawner.dynamic_users = True
    def start_user(spawner):
        import os, pwd, grp
        username = spawner.user.name
        path = os.path.join('/usr/share/notebooks', username)
        if not os.path.exists(path):
                os.mkdir(path, 0o755)
                uid = pwd.getpwnam(username).pw_uid
                gid = grp.getgrnam(username).gr_gid
                os.chown(path, uid, gid)
