Docker In Docker - SSL problems


Probably it's too late to answer, but I will put it here in case of other strangers with similar problem.
I would suggest to check MTU in parent and child containers.

ip addr | grep mtu

In case you see that difference in MTU
e.g.

3: eth0@if14: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1402 qdisc noqueue state UP group default4: docker0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default

it needs to be corrected to be the same.
e.g.

ip link set dev eth0 mtu 1500
