If the development environment (Docker) does not work when upgrading Docker, ... Let's return to Docker when it was working normally. (I really don't want to do this !! lol)
Download the version when it was working normally from Docker for Mac release notes.
Open the downloaded file (Docker.dmg). When asked if you want to overwrite, you can overwrite without asking questions (laugh)
Open Docker in your application folder.
At this time, the update dialog may appear, but be careful not to press "Install Update" by mistake. However, it's okay to make a mistake! You just have to start over from step 1 again (laughs)
#Check docker version docker -v Docker version 19.03.13 # docker-Compose version check docker-compose -v docker-compose version 1.27.4
Now I can finally return to peaceful days. .. .. I don't want to use an older version, but when do you update? I'll be careful to reflexively press the update button (laughs)
