Do containers use same kernel? - Ask Ubuntu


i wanted know if containers running on particular linux machine use same underlying host kernel. read yes, use same underlying host's kernel , hence light-weight , fast.

i not sure if different linux flavors have same kernel @ heart.

if of them have same kernel @ heart, first assumption right.

but, if linux flavors don't have same kernel... first assumption (that containers use host's kernel) must wrong. further, must indicate image -using containers built- contain whole os including kernel.

you seem bit confused. there no single 1 thing known "linux". there many linux versions, blessed linus torvalds, , there many different versions of that, employed different vendors. whichever kernel given host machine running 1 kernel on particular system, , shared containers running on machine, not exact same kernel running on machine.
