Open a blank document and choose 'custom shape tool'.



Open the dropbox 'shape' and choose the octagon shape



Go to your document and hold the shift key (to constrain the proportions) and draw you octagon.



Duplicate the layer (ctrl+J), open the transform tool (ctrl+T) press shift+alt and drag the duplicate inwards

You could also create the shape and set the stroke to about 20 pixels and with a darker shade of blue

Don't forget, you can add in the gradient using a layer style on the Octagon shape layer.
