a9s CLI

anynines provides a command line tool called a9s to facilitate application development, devops tasks and interact with selected anynines products.

Prerequisites​

  • MacOS / Linux.
  • Using the backup/restore feature of a8s PostgreSQL requires an S3 compatible endpoint.
  • Install Go (if you want go env to identify your OS and arch).
  • Install Git.
  • Install Docker.
  • Install Kubectl.
  • Install Kind and/or Minikube.

Installing the CLI​

In order to install the a9s CLI execute the following shell script:

RELEASE=$(curl -L -s https://a9s-cli-v2-fox4ce5.s3.eu-central-1.amazonaws.com/stable.txt); OS=$(go env GOOS); ARCH=$(go env GOARCH); curl -fsSL -o a9s https://a9s-cli-v2-fox4ce5.s3.eu-central-1.amazonaws.com/releases/$RELEASE/a9s-$OS-$ARCH
    
sudo chmod 755 a9s
sudo mv a9s /usr/local/bin

This will download the a9s binary suitable for your architecture and move it to /usr/local/bin. Depending on your system you have to adjust the PATH variable or move the binary to a folder that's already in the PATH.
