Packaging¶
Added a technical preview for cri-docker (previously known as dockershim).
Fixed an issue wherein killing containerd caused systemd to stop docker.
Networking¶
Fixed an issue wherein swarm service VIPs timed out from Windows containers, resulting in the following error in dockerd event logs:
Failed to add ILB policy for service service […] failed during hnsCallRawResponse: hnsCall failed in Win32: The specified port already exists.
The Windows Operating System update KB4577668 introduced the issue on October 13, 2020, affecting all versions of MCR (FIELD-3310).
Known issues¶
Centos and RHEL 7.x kernels may experience memory exhaustion due to slab cache usage. Because this is a kernel feature, the issue cannot be resolved with MCR code.
Workarounds:
(Recommended) Update to a kernel that supports setting
cgroups.memory=nokmem
and apply the change (for customers using Centos or RHEL 7.7 and above).Increase the memory available to the machine for slab usage.
