Containers hold most resources when they arrive on your ship. The resources can be accessed using loaders connected to pipes, or in some cases, the container will be attached directly to the relevant equipment, such as with the FTL Drive. When the container is empty, it will disappear and automatically be replaced if there is an available container of the same type. There is currently no way to create or fill a container. Fluid resources can only be sold to a trader while in a container.
