⁠change

phusion/baseimage:latest Go 1.6 supports vendoring by default.

⁠gcr.io/google_appengine/golang

gcr.io/google_appengine/golang is a docker⁠ base image that bundles the latest version of Go⁠ installed from golang.org⁠.

It serves as a base for Go apps running on Google App Engine Managed VMs⁠.

⁠Notes

⁠Vendoring

Your application will be built using Go 1.5 inside the docker instance without the experimental vendoring support. To enable Go 1.5 experimental vendoring support, set the environment variable like this:

    FROM gcr.io/google_appengine/golang
    ENV GO15VENDOREXPERIMENT 1
    COPY . /go/src/app
    RUN go-wrapper install -tags appenginevm

For Go 1.5 vendoring details, see the documentation for the go command⁠ and the design document⁠. As of 2015-08-27, the following Go package management apps support this new flag: godep⁠, govendor⁠, and glide⁠.

⁠Using Go 1.4

To use Go 1.4, edit the app.yaml file and remove the "runtime: go" line then provide your own Dockerfile in the same directory as the app.yaml file, like this:

    FROM golang:1.4-onbuild
    COPY . /go/src/app
    RUN go-wrapper install -tags appenginevm

⁠Usage

• Create a Dockerfile in your Go application directory with the following content:

    FROM gcr.io/google_appengine/golang
  
    COPY . /go/src/app
    RUN go-wrapper install -tags appenginevm
  

  Copy

• Run the following command in your application directory:

    docker build -t my/app .
  

  Copy
