#8939

## Description of change

When setting up the uniter remote watcher, only hook up the upgradeseries watcher on IAAS models.

As a driveby, move a couple of storage watcher vars left in the wrong place.

## QA steps

Ensure CAAS deployments work again.

juju

juju is devops distilled.

Juju enables you to use Charms to deploy your application architectures to EC2, OpenStack, Azure, GCE, your data center, and even your own Ubuntu based laptop. Moving between models is simple giving you the flexibility to switch hosts whenever you want — for free.

For more information, see the docs.

Getting started

juju is written in Go (http://golang.org), a modern, compiled, statically typed, concurrent language. This document describes how to build juju from source.

If you are looking for binary releases of juju, they are available in the snap store

snap install juju --classic

Installing Go

Juju's source code currently depends on Go 1.10. One of the easiest ways to install golang is from a snap. You may need to first install the snap client. Installing the golang snap package is then as easy as

snap install go --channel=1.10/stable --classic

You can read about the "classic" confinement policy here

If you want to use apt, then you can add the Golang Gophers PPA and then install by running the following

sudo add-apt-repository ppa:gophers/archive
sudo apt-get update
sudo apt install golang-1.10

Alternatively, you can always follow the official binary installation instructions

Setting GOPATH

When working with the source of Go programs, you should define a path within your home directory (or other workspace) which will be your GOPATH. GOPATH is similar to Java's CLASSPATH or Python's ~/.local. GOPATH is documented online at http://golang.org/pkg/go/build/ and inside the go tool itself

go help gopath

Various conventions exist for naming the location of your GOPATH, but it should exist, and be writable by you. For example

export GOPATH=${HOME}/work
mkdir $GOPATH

will define and create $HOME/work as your local GOPATH. The go tool itself will create three subdirectories inside your GOPATH when required; src, pkg and bin, which hold the source of Go programs, compiled packages and compiled binaries, respectively.

Setting GOPATH correctly is critical when developing Go programs. Set and export it as part of your login script.

Add $GOPATH/bin to your PATH, so you can run the go programs you install:

PATH="$GOPATH/bin:$PATH"

Getting juju

The easiest way to get the source for juju is to use the go get command.

go get -d -v github.com/juju/juju/...

This command will checkout the source of juju and inspect it for any unmet Go package dependencies, downloading those as well. go get will also build and install juju and its dependencies. To checkout without installing, use the -d flag. More details on the go get flags are available using

go help get

At this point you will have the git local repository of the juju source at $GOPATH/src/github.com/juju/juju. The source for any dependent packages will also be available inside $GOPATH. You can use git pull --rebase, or the less convenient go get -u github.com/juju/juju/... to update the source from time to time. If you want to know more about contributing to juju, please read the CONTRIBUTING companion to this file.

Installing prerequisites

Making use of Makefile

The juju repository contains a Makefile, which is the preferred way to install dependencies and other features. It is advisable, when installing juju from source, to look at the Makefile, located in $GOPATH/src/github.com/juju/juju/Makefile.

Dependencies

Juju needs some dependencies in order to be installed and the preferred way to collect the necessary packages is to use the provided Makefile. The target godeps will download the go packages listed in dependencies.tsv. The following bash code will install the dependencies.

cd $GOPATH/src/github.com/juju/juju
export JUJU_MAKE_GODEPS=true
make godeps

Runtime Dependencies

You can use make install-dependencies or, if you prefer to install them manually, check the Makefile target.

This will add some PPAs to ensure that you can install the required golang and mongodb-server versions for precise onwards, in addition to the other dependencies.

Build Dependencies

Before you can build Juju, see Dependency management section of CONTRIBUTING to ensure you have build dependencies setup.

Building juju

go install -v github.com/juju/juju/...

Will build juju and install the binary commands into $GOPATH/bin. It is likely if you have just completed the previous step to get the juju source, the install process will produce no output, as the final executables are up-to-date.

If you do see any errors, there is a good chance they are due to changes in juju's dependencies. See the Dependency management section of CONTRIBUTING for more information on getting the dependencies right.

Using juju

After following the steps above you will have the juju client installed in GOPATH/bin/juju. You should ensure that this version of juju appears earlier in your path than any packaged versions of juju, or older Python juju commands. You can verify this using

which juju

You should be able to bootstrap a local model now with the following:

juju bootstrap localhost

Installing bash completion for juju

make install-etc

Will install Bash completion for juju cli to /etc/bash_completion.d/juju. It does dynamic completion for commands requiring service, unit or machine names (like e.g. juju status , juju ssh , juju terminate-machine <machine#>, etc), by parsing cached juju status output for speedup. It also does command flags completion by parsing juju help ... output.

Building Juju as a Snap Package

Building

Make sure your snapcraft version is >= 2.26. Run snapcraft at the root of the repository. A snap will build.

Current State

Classic mode.

Known Issues

None. The snap shares your current credentials and environments as expected with a debian installed version.

Needed for confinement

To enable strict mode, the following bugs need to be resolved, and the snap updated accordingly.
