This charm will install a snap-store-proxy on local premises. In order to do
this, a registration bundle is required. This registration bundle can be
obtained via the snap store-admin.
The charm can be installed in two ways. The preferred way is to use the
snap-store itself, which means that the machine instances on which the
snap-store-proxy-charm is installed, needs to be to connect to the store.
The other way is, to download the snap-store-proxy*.snap and the
core20-*.snap and attach these as resources to the snap-store-proxy-charm
during installation. After installation a resource can be updates via juju,
by attaching a newer resource. This will be the only way to update the charm.
It is not possible to switch between these 2 modes of installation.
Basic install
An example juju-bundle, that can be used for installation:
applications:
postgresql:
charm: ch:postgresql
channel: stable
num_units: 1
snap-store-proxy:
charm: ch:snap-store-proxy-charm
num_units: 1
relations:
- - postgresql:db-admin
- snap-store-proxy:db-admin
Resource based install
When using a resource based install the core20 an snap-store-proxy snap’s can
be downloaded via the command: snap download core20 and
snap download snap-store-proxy. Once this is done the following juju bundle
can be used for installation.
applications:
postgresql:
charm: ch:postgresql
channel: stable
num_units: 1
snap-store-proxy:
num_units: 1
resources:
snap-store-proxy: snap-store-proxy_<number>.snap
core: core20_<number>.snap
relations:
- - postgresql:db-admin
- snap-store-proxy:db-admin
Configuration
In both the installation examples above, the charm still needs to be
registered. This registration has to be done via the snap store-admin and
will produce a registration file. This registration file needs to be added
to the charm option called registration_bundle.
I this file is called register.json the following command can be used:
juju config snap-store-proxy \
registration_bundle=$(cat <output of store-admin register>)
Obviously this can also be added to the juju deployment bundle, both methods, registering during installation, or after installation, are supported.
