Truncate docker logs

Reading time: < 1 minute Sometimes when a container is running for a long time especially when docker logs command is called the logs dump is extra long and then a recurrent search on google for reminding how to truncate a file is mandatory for avoiding this repeating task this is the trick that it saves me from that uncomfortable long log dump.

truncate -s 0 $(docker inspect --format='{{.LogPath}}' CONTAINER_ID)

Windows 10: enable/disable Hyper-V from CLI

Reading time: < 1 minute Assuming we're running a Windows shell with administrator privileges, using next commands is possible to enable, or disable, Hyper-V. In my case this is needed because when Hyper-V is running Virtualbox only can run 32bit virtual machines. I require Microsoft VM manager Hyper-V because I also run Docker for Windows and it's a requirement.

#enable Hyper-V
dism.exe /Online /Enable-Feature:Microsoft-Hyper-V /All

#disable Hyper-V
dism.exe /Online /Disable-Feature:Microsoft-Hyper-V
