Functions

func CreateClientOpts 

func CreateClientOpts(ctx context.Context, env Env) ([]client.Opt, error)

Adapted from client.FromEnv

Supported environment variables: DOCKER_HOST to set the url to the docker server. DOCKER_API_VERSION to set the version of the API to reach, leave empty for latest. DOCKER_CERT_PATH to load the TLS certificates from. DOCKER_TLS_VERIFY to enable or disable TLS verification, off by default.

func HasFinished added in v0.14.0

Sadly, certain versions of docker return an error if the client requests buildkit. We have to infer whether it supports buildkit from version numbers.
