[Docker for Windows] Certificate Error Solution

Problem Definition: After installing “Docker for Windows” on Windows 10 Professional box, when you type any docker command or lets say for eg. docker ps, you get following error:

 

could not read CA certificate "C:\\Users\\UserName\\.docker\\machine\\machines\\default\\ca.pem": open C:\\Users\\UserName\\.docker\machine\machines\default\ca.pem: The system cannot find the path specified.

 

Solution: you need to delete all DOCKER_* environment variables from your machine. Which needs to be done in 2 steps:

Step 1> Go to Control Panel\All Control Panel Items\System Then click Advanced system settings, In System Propteries, Go to Advanced Tab and Click Environment Variables. Delete all DOCKER_* from System/User variables.

Step 2> Remove DOCKER_* from command prompt or PowerShell, i used PowerShell. using following steps:

[Environment]::SetEnvironmentVariable("DOCKER_CERT_PATH", $null, "User")

[Environment]::SetEnvironmentVariable("DOCKER_HOST", $null, "User")

[Environment]::SetEnvironmentVariable("DOCKER_MACHINE_NAME", $null, "User")

[Environment]::SetEnvironmentVariable("DOCKER_TLS_VERIFY", $null, "User")

[Environment]::SetEnvironmentVariable("DOCKER_TOOLBOX_INSTALL_PATH", $null, "User")

Now Close and Open Powershell again and now run docker ps it will work fine without any Certificate Error.

Instalar ZSH no linux

Se preferir via curl:

curl -L http://install.ohmyz.sh | sh

Ou se quiser manualmente, também é bem fácil:

Copie o projeto com o comando:

git clone git://github.com/robbyrussell/oh-my-zsh.git ~/.oh-my-zsh

Crie uma nova configuração do arquivo zsh copiando o template fornecido:

cp ~/.oh-my-zsh/templates/zshrc.zsh-template ~/.zshrc

Defina Zsh como seu shell principal:

chsh -s /bin/zsh

E pronto. Basta digitar no terminal ‘zsh’ e ele será aberto.
