Problem

When I use docker to work with the shared workspace with host under Ubuntu, I find that files created by docker user is owned by root. This is not the same with macOS.

Maybe this is becuase docker is run by root user and the default user mapping mechanism is to map container-root to host-user or host-root. So can I map the container-root or container-any-user to host-current-user?

Fortunately the latest docker supports the re-map the container user to any host user via Linux namespace. Refer to this.

Enable LDAP over SSL (LDAPS) for Microsoft Active Directory servers

Microsoft active directory servers will default to offer LDAP connections over unencrypted connections (boo!).

The steps below will create a new self signed certificate appropriate for use with and thus enabling LDAPS for an AD server. Of course the "self-signed" portion of this guide can be swapped out with a real vendor purchased certificate if required.

Steps have been tested successfully with Windows Server 2012R2, but should work with Windows Server 2008 without modification. Requires a working OpenSSL install (ideally Linux/OSX) and (obviously) a Windows Active Directory server.

• Create root certificate
• Import root certificate into trusted store of domain controller

Ansible Vault Environment Variable

Per http://docs.ansible.com/ansible/playbooks_vault.html you can set an environment variable to use a password file for vault access. We can use this to create an environment variable to hold the password.

Password Script

Copy vault-env from this project to ~/bin. Then add this to your ~/.bashrc:

export ANSIBLE_VAULT_PASSWORD_FILE=~/bin/vault-env

Configuring nginx for SSL SNI vhosts

Gotchas

• Note that SHA2 hash algorithm may be not supported on older systems (Windows XP, Windows 2003, among others).
• Be aware that mandatory https on SNI vhosts eliminate [Internet Explorer on Windows XP, among others] (http://en.wikipedia.org/wiki/Server_Name_Indication#Web_browsers.5B6.5D).

Remarks

• My version of konklones SSL config does not have SPDY support(my nginx+openssl does not support it)
• You need a default ssl server (example.org-default.conf).
• Some SSL-options have to be unique across your instance, so it's easier to have them in a common file(ssl.conf).

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.
