Helm Classic - A Kubernetes Package Manager
Helm and Deployment Manager have recently joined forces to make deploying and managing software on Kubernetes as simple as possible. The combined effort now lives in the Kubernetes GitHub organization at kubernetes/helm.
For more information about the architecture of
kubernetes/helm read the architecture documentation.
Helm Classic bootstraps your Kubernetes cluster with Charts that provide ready-to-use workloads like:
- A Redis cluster
- A Postgres database
- An HAProxy edge load balancer
Installing Helm Classic
From a Linux or Mac OS X client:
curl -s https://get.helm.sh | bash
Grab a prebuilt binary from the latest release:
- Mac OS X 64 Bit: https://storage.googleapis.com/helm-classic/helmc-latest-darwin-amd64
- Mac OS X 32 Bit: https://storage.googleapis.com/helm-classic/helmc-latest-darwin-386
- Linux 64 Bit: https://storage.googleapis.com/helm-classic/helmc-latest-linux-amd64
- Linux 32 Bit: https://storage.googleapis.com/helm-classic/helmc-latest-linux-386
Once you've downloaded the appropriate binary for your OS and architecture, ensure that it's executable:
chmod +x helmc
And then put it on your
If you are a user of the original Helm tool (versions prior to v0.7.0), take note that Helm Classic is a re-branding of that tool-- new name, same great taste!
Helm Classic is fully compatible with previously existing Helm charts!
Anyone migrating to Helm Classic from an older version should complete the following steps to fully replace their existing tool with Helm Classic. Doing so will clear the path for eventual installation of the new and improved Helm (kubernetes/helm).
First, you may optionally define a custom home directory for use by Helm Classic. If opting for this, the instruction should be added to your shell's profile.
Next, we migrate the contents from its old location to its new location (because the default location has changed).
$ mv $(helm home) $(helmc home)
Finally, remove the old version:
$ rm $(which helm)
You may now use the new binary,
helmc, just as you previously used
helm. Soon, the
helm name will be taken over by the new and improved Helm (kubernetes/helm) and you will be able to make use of
helmc in parallel with
helm for as long as you have that need.
Helm Classic requires an appropriately wired
kubectl client to speak with a running Kubernetes cluster.
Using Helm Classic
To quickly install a redis cluster:
$ helmc update ---> Cloning into '$HOME/.helmc/cache/charts'... ---> Updating cache from https://github.com/helmc/charts ---> Done $ helmc search redis ---> redis-cluster (redis-cluster 0.0.5) - Highly available Redis cluster with multiple sentinels and standbys. ---> redis-standalone (redis-standalone 0.0.1) - Standalone Redis Master $ helmc info redis-cluster Name: redis-cluster Home: http://github.com/deis/redis-cluster Version: 0.0.5 Description: Highly available Redis cluster with multiple sentinels and standbys. Details: This package provides a highly available Redis cluster with multiple sentinels and standbys. Note the `redis-master` pod is used for bootstrapping only and can be deleted once the cluster is up and running. $ helmc install redis-cluster ---> No chart named "redis-cluster" in your workspace. Fetching now. ---> Fetched chart into workspace $HOME/.helmc/workspace/charts/redis-cluster ---> Running `kubectl create -f` ... services/redis-sentinel pods/redis-master replicationcontrollers/redis replicationcontrollers/redis-sentinel ---> Done
To fetch, modify and install a chart out of your local workspace:
$ helmc update ---> Updating cache from https://github.com/helm/charts ---> Done $ helmc fetch redis-standalone redis ---> Fetched chart into workspace $HOME/.helmc/workspace/charts/redis ---> Done $ helmc edit redis $ helmc install redis ---> Running `kubectl create -f` ... replicationcontrollers/redis-standalone ---> Done
Building the Helm Classic CLI
- Make sure you have a
kubectlclient installed and configured to speak with a running Kubernetes cluster.
- Helm Classic utilizes a containerized build and test process. Making use of the containerized development environment only requires
makeand a local Docker daemon or
git clone https://github.com/helm/helm-classic.git cd helm-classic make bootstrap # installs all of helm classic's dependencies make build # generates bin/helmc binary ./bin/helmc # prints usage # optional make install # installs helmc system-wide helmc # prints usage
