This talk will discuss: • The problems with container networking and the cost of overlay networks • When you might not want to swap fast in-process communication with slow and unreliable HTTP • What happens to the output from helpful debugging tools like ps and top when containers get involved • Why referring to containers as lightweight virtual machines can be dangerous This talk should be equal parts helpful tips and cautionary tales, topped with just the right amount of snark. Afterwards you should be better prepared to start using containers in your systems.

The Registration desk is located in the main lobby/reception of the FT building which is on the 2nd floor (entrance is directly off Southwark Bridge). Security will escort arrivals in groups to the conference suite on the 6th floor. • Beer and pizzas will be served up at approx. 20:15 and the meetup will end at 22:00 and all attendees must exit the building by 22:30. Why have you started charging for your meetup events? • We are charging a nominal £5 entry for our meetup events primarily to reduce the very high level 'no shows' that we have had in the past. This is very frustrating for those that really want to go but end up not being able to attend as all the spots have been taken.The 'waitlist' concept relies on 'no shows' actually releasing their space, and we find that this just doesn't happen. 'No shows' also cause difficulties for us in terms of food and drink provision and event checkin/security. • All food and drink is provided due the generosity of our sponsors and the entry fee's are used towards the general operation of the group. As we are a non-profit making community association, any annual surplus from both sponsorship and attendance fees will be donated to IT related charities. Do I have to bring my printed ticket to the event? • Yes - It really helps us if you can bring your Eventbrite paper or online ticket (containing the QR code) to the checkin desk at the event. What is the refund policy? • In the event of the event being cancelled by the organisers, then a full refund will be made. No other refunds will be made under any circumstances. You can transfer you ticket to someone else via Eventbrite. The name on the registration/ticket doesn't match the attendee. Is that okay? • As we are using corporate facilities to host the meetup, security will perform a name check at check-in so its much easier if for everyone if you purchase your ticket in the correct name. Are there ID requirements or an age limit to enter the event? • ID will be required if you are not the named ticket holder. Our group sponsors provide alcholic drinks during the meetup session so you have to be over 18 to benefit from those. Click here to register and purchase ticket
