Install Private Supermarket

The source code for Chef Supermarket is located at the following URLs:


A private Chef Supermarket has the following requirements:

  • An working Chef Infra Server, which acts as the OAuth 2.0 provider
  • A user account on the Chef Infra Server with admins privileges
  • A key for the user account on the Chef server
  • An x86_64 compatible Linux host with at least 2 GB memory
  • System clocks synchronized on the Chef Infra Server and Supermarket hosts
  • Sufficient disk space on host to meet project cookbook storage capacity or credentials to store cookbooks in an Amazon Simple Storage Service (S3) bucket

Considerations with regard to storage capacity:

  • PostgreSQL database size will grow linearly based on the number of cookbooks and the number of cookbook versions published
  • Redis database size is negligible as it is used only for background job queuing, and to cache a small number of API responses
  • Cookbook storage growth is entirely dependent on the size of the cookbooks published. Cookbooks that include binaries or other large files will consume more space than code-only cookbooks
  • Opting to run a private Supermarket with off-host PostgreSQL, Redis, and cookbook store is less a decision about storage sizing; it is about data service uptime, backup, and restore procedure for your organization
  • As a point of reference: as of May 2021 after six years of operation, the public Supermarket has approx 83,000 users, 4,000 cookbooks with a total of 27,000 versions published. The PostgreSQL database is 435 MB, and the S3 bucket containing the published community cookbooks is 3.1 GB

Chef Identity

Chef Identity (also referred to as oc-id) is an OAuth 2.0 authentication and authorization service packaged with the Chef Infra Server. Chef Identity must be configured to run with a private Chef Supermarket, after which users may use the same credentials to access the Chef Supermarket as they do to access the Chef Infra Server.


The Chef Supermarket server must be able to reach (via HTTPS) the specified chef_server_url during OAuth 2.0 negotiation. This type of issue is typically with name resolution and firewall rules.


To configure Chef Supermarket to use Chef Identity, do the following:

  1. Log on to the Chef Infra Server via SSH and elevate to an admin-level user. If running a multi-node Chef Infra Server cluster, log on to the node acting as the primary node in the cluster.

  2. Update the /etc/opscode/chef-server.rb configuration file.

    To define OAuth 2 information for Chef Supermarket, create a Hash similar to:

    oc_id['applications'] ||= {}
        oc_id['applications']['supermarket'] = {
          'redirect_uri' => '',
  3. Reconfigure the Chef Infra Server.

    sudo chef-server-ctl reconfigure
  4. Retrieve Supermarket’s OAuth 2.0 client credentials:

    Depending on your Chef Infra Server version and configuration (see chef-server.rb), you can retrieve this from chef-server-ctl oc-id-show-app supermarket or find it in /etc/opscode/oc-id-applications/supermarket.json:

      "name": "supermarket",
      "uid": "0bad0f2eb04e935718e081fb71asdfec3681c81acb9968a8e1e32451d08b",
      "secret": "17cf1141cc971a10ce307611beda7ffadstr4f1bc98d9f9ca76b9b127879",
      "redirect_uri": "",
      "confidential": true

    You will need the uid and secret later on during the setup process for Chef Supermarket.


Add as many Chef Identity applications to the /etc/opscode/chef-server.rb configuration file as necessary. A JSON file is generated for each application added, which contains the authentication tokens for that application. The secrets are added to the Chef Identity database and are available to all nodes in the Chef Infra Server front end group. The generated JSON files do not need to be copied anywhere.


The redirect URL specified MUST match the FQDN of the Chef Supermarket server. The URI must also be correct: /auth/chef_oauth2/callback. Otherwise, an error message similar to The redirect uri included is not valid. will be shown.

Install Supermarket

To install a private Chef Supermarket use the supermarket-omnibus-cookbook. This cookbook is available from the public Chef Supermarket.

  • The supermarket-omnibus-cookbook cookbook is attribute-driven; use a custom cookbook to specify your organization’s unique node[supermarket_omnibus] attribute values.
  • The custom cookbook is a wrapper around supermarket-omnibus-cookbook, which performs the actual installation of the Chef Supermarket packages, and then writes the custom node[supermarket_omnibus] values to /etc/supermarket/supermarket.json.
  • The Chef Supermarket package itself contains an internal cookbook which configures the already-installed package using the attributes defined in /etc/supermarket/supermarket.json.


In general, for production environments Chef recommends to start running Chef Supermarket with small virtual machines, and then increase the size of the virtual machine as necessary. Put the /var/opt/supermarket directory on a separate disk, and then use LVM so that may be expanded.

Create a Wrapper

A wrapper cookbook is used to define project- and/or organization-specific requirements around a community cookbook.

In the case of installing a private Chef Supermarket, Chef recommends the use of a wrapper cookbook to specify certain attributes that are unique to your organization, while enabling the use of the generic installer cookbook which, in turn, installs the Chef Supermarket package behind your firewall.

All of the keys under node['supermarket_omnibus'] are written out as /etc/supermarket/supermarket.json. Add other keys as needed to override the default attributes specified in the Chef Supermarket omnibus package.

For example:

default['supermarket_omnibus']['chef_server_url'] = ''
default['supermarket_omnibus']['chef_oauth2_app_id'] = '14dfcf186221781cff51eedd5ac1616'
default['supermarket_omnibus']['chef_oauth2_secret'] = 'a49402219627cfa6318d58b13e90aca'
default['supermarket_omnibus']['chef_oauth2_verify_ssl'] = false
default['supermarket_omnibus']['fqdn'] = ''

On your workstation, generate a new cookbook using the chef command line interface:

  1. Generate the cookbook:

    chef generate cookbook my_supermarket_wrapper
  2. Change directories into that cookbook:

    cd my_supermarket_wrapper
  3. Defines the wrapper cookbook’s dependency on the supermarket-omnibus-cookbook cookbook. Open the metadata.rb file of the newly-created cookbook, and then add the following line:

    depends 'supermarket-omnibus-cookbook'
  4. Save and close the metadata.rb file.

  5. Open the /recipes/default.rb recipe located within the newly-generated cookbook and add the following content:

    include_recipe 'supermarket-omnibus-cookbook'

    This ensures that the default.rb file in the supermarket-omnibus-cookbook is run.

Define Attributes

Define the attributes for the Chef Supermarket installation and how it connects to the Chef Infra Server. One approach would be to hard-code attributes in the wrapper cookbook’s default.rb recipe. A better approach is to place these attributes in a data bag, and then reference them from the recipe. For example, the data bag could be named apps and then a data bag item within the data bag could be named supermarket.

The following attribute values must be defined:

  • chef_server_url
  • chef_oauth2_app_id
  • chef_oauth2_secret

Once configured, you can get the chef_oauth2_app_id and chef_oauth2_secret values from your Chef Infra Server within /etc/opscode/oc-id-applications/supermarket.json:

For chef_server_url, enter in the URL of your chef server. For chef_oauth2_app_id, enter in the uid from /etc/opscode/oc-id-applications/supermarket.json For chef_oauth2_secret, enter in the secret from /etc/opscode/oc-id-applications/supermarket.json

To define these attributes, do the following:

  1. Open the /recipes/default.rb file and add the following, BEFORE the include_recipe line that was added in the previous step. This example uses a data bag named apps and a data bag item named supermarket:

    app = data_bag_item('apps', 'supermarket')
  2. Set the attributes from the data bag:

    node.override['supermarket_omnibus']['chef_server_url'] = app['chef_server_url']
    node.override['supermarket_omnibus']['chef_oauth2_app_id'] = app['chef_oauth2_app_id']
    node.override['supermarket_omnibus']['chef_oauth2_secret'] = app['chef_oauth2_secret']

    When finished, the /recipes/default.rb file should have code similar to:

    app = data_bag_item('apps', 'supermarket')
    node.override['supermarket_omnibus']['chef_server_url'] = app['chef_server_url']
    node.override['supermarket_omnibus']['chef_oauth2_app_id'] = app['chef_oauth2_app_id']
    node.override['supermarket_omnibus']['chef_oauth2_secret'] = app['chef_oauth2_secret']
    include_recipe 'supermarket-omnibus-cookbook'
  3. Save and close the /recipes/default.rb file.


If you are running your private Supermarket in AWS, you may need to set an additional attribute for the node’s public IP address:

node.override['supermarket_omnibus']['config']['fqdn'] = your_node_public_ip

Upload the Wrapper

The wrapper cookbook around the supermarket-omnibus-cookbook cookbook must be uploaded to the Chef Infra Server, along with any cookbooks against which the supermarket-omnibus-cookbook cookbook has dependencies.

To upload the cookbooks necessary to install Chef Supermarket, do the following:

  1. Install Berkshelf:

    berks install
  2. Change directories into ~/.berkshelf/cookbooks:

    cd ~/.berkshelf/cookbooks
  3. Upload all cookbooks to the Chef Infra Server:

    knife cookbook upload -a
  4. Change directories into the location in which the wrapper cookbook was created:

    cd path/to/wrapper/cookbook/
  5. Upload the wrapper cookbook to the Chef Infra Server:

    knife cookbook upload -a

Bootstrap Supermarket

Bootstrap the node on which Chef Supermarket is to be installed. For example, to bootstrap a node running Ubuntu on Amazon Web Services (AWS), the command is similar to:

knife bootstrap ip_address -N supermarket-node -x ubuntu --sudo


  • -N defines the name of the Chef Supermarket node: supermarket-node
  • -x defines the (ssh) user name: ubuntu
  • --sudo ensures that sudo is used while running commands on the node during the bootstrap operation

When the bootstrap operation is finished, do the following:

  1. Edit the node to add the wrapper cookbook’s /recipes/default.rb recipe to the run-list:

    knife node edit supermarket-node

    where supermarket-node is the name of the node that was just bootstrapped.

  2. Add the recipe to the run-list:

    "run_list": [
  3. Start Chef Infra Client on the newly-bootstrapped Chef Supermarket node. For example, using SSH:

    ssh ubuntu@your-supermarket-node-public-dns
  4. After accessing the Chef Supermarket node, run Chef Infra Client:

    sudo chef-client

Install Supermarket Directly (without a cookbook)

While there are many benefits to using the cookbook method to install Supermarket, there are also cases where it’s simpler to set up the Supermarket installation manually. These steps will walk you through the process of manually configuring your private Supermarket server.

Before following these steps, be sure to complete the OAuth setup process detailed in the Chef Identity section of this guide.

  1. Download the correct package of Chef Supermarket for your operating system from Chef Downloads.

  2. Install Supermarket using the appropriate package manager for your distribution:

    • For Ubuntu:

      dpkg -i /path/to/package/supermarket*.deb
    • For RHEL / CentOS:

      rpm -Uvh /path/to/package/supermarket*.rpm
  3. Run the reconfigure command to complete the initial installation:

    sudo supermarket-ctl reconfigure
  4. Create an /etc/supermarket/supermarket.json file and add the following information, substituting the values for each configuration option with the OAuth 2.0 client credentials that were created in the previous section:

        "chef_server_url": "",
        "chef_oauth2_app_id": "0bad0f2eb04e935718e081fb71asdfec3681c81acb9968a8e1e32451d08b",
        "chef_oauth2_secret": "17cf1141cc971a10ce307611beda7ffadstr4f1bc98d9f9ca76b9b127879",
        "fqdn": "",
        "chef_oauth2_verify_ssl": false


    • "chef_server_url" should contain the FQDN of your Chef Infra Server. Note that if you’re using a non-standard SSL port, this much be appended to the URL. For example:
    • "chef_oauth2_app_id" should contain the "uid" value from your OAuth credentials
    • "chef_oauth2_secret" should contain the "secret" value from your OAuth credentials
    • chef_oauth2_verify_ssl is set to false, which is necessary when using a self-signed certificate without a properly configured certificate authority
    • fqdn should contain the desired URL that will be used to access your private Supermarket. If not specified, this default to the FQDN of the machine
  5. Issue another reconfigure command to apply your changes:

    sudo supermarket-ctl reconfigure

Connect to Supermarket

To reach the newly spun up private Chef Supermarket, the hostname must be resolvable from a workstation. For production use, the hostname should have a DNS entry in an appropriate domain that is trusted by each user’s workstation.

  1. Visit the Chef Supermarket hostname in the browser. A private Chef Supermarket will generate and use a self-signed certificate, if a certificate is not supplied as part of the installation process (via the wrapper cookbook).
  2. If an SSL notice is shown while connecting to Chef Supermarket via a web browser, accept the SSL certificate. A trusted SSL certificate should be used for private Chef Supermarket that is used in production.
  3. After opening Chef Supermarket in a web browser, click the Create Account link. A prompt to log in to the Chef Infra Server is shown, but only if the user is not already logged in. Authorize the Chef Supermarket to use the Chef Infra Server account for authentication.


The redirect URL specified for Chef Identity MUST match the fqdn hostname of the Chef Supermarket server. The URI must also be correct: /auth/chef_oauth2/callback. Otherwise, an error message similar to The redirect uri included is not valid. will be shown.

Customize Supermarket

Chef Supermarket is a Ruby on Rails application with a PostgreSQL database. The private Chef Supermarket configuration may be scaled-out, such as using an external database, using an external cache, and using an external cookbook storage location.

External Database

A Chef Supermarket installation can use an external database running PostgreSQL (9.3 or higher) and with the pgpsql and pg_trgm installed and loaded. The public Chef Supermarket uses Amazon Relational Database Service (RDS). To use an external database, configure the following attributes in the /recipes/default.rb recipe of the wrapper cookbook:

node.override['supermarket_omnibus']['config']['postgresql']['enable'] = false
node.override['supermarket_omnibus']['config']['database']['user'] = 'supermarket'
node.override['supermarket_omnibus']['config']['database']['name'] = 'supermarket'
node.override['supermarket_omnibus']['config']['database']['host'] = ''
node.override['supermarket_omnibus']['config']['database']['port'] = '5432'
node.override['supermarket_omnibus']['config']['database']['pool'] = '25'
node.override['supermarket_omnibus']['config']['database']['password'] = 'topsecretneverguessit'

External Cache

Chef Supermarket installations can also use an external cache store. The public Chef Supermarket uses Redis on Amazon ElastiCache. One Redis instance per private Chef Supermarket application server may be run safely. Use Redis 2.8 (or higher) for a high availability pair. To use an external cache, configure the following attributes in the /recipes/default.rb recipe of the wrapper cookbook:

node.override['supermarket_omnibus']['config']['redis']['enable'] = false
node.override['supermarket_omnibus']['config']['redis_url'] = 'redis://your-redis-instance:6379'

External Cookbook Storage

Cookbook artifacts—tar.gz artifacts that are uploaded to Chef Supermarket when sharing a cookbook—can be stored either on the local filesystem of the Chef Supermarket node (/var/opt/supermarket/data by default) or in an Amazon Simple Storage Service (S3) bucket. To use an S3 bucket, configure the following attributes in the /recipes/default.rb recipe of the wrapper cookbook:

node.override['supermarket_omnibus']['config']['s3_access_key_id'] = 'yourkeyid'
node.override['supermarket_omnibus']['config']['s3_bucket'] = 'all-our-awesome-cookbooks'
node.override['supermarket_omnibus']['config']['s3_region'] = 'some-place-3'
node.override['supermarket_omnibus']['config']['s3_secret_access_key'] = 'yoursecretaccesskey'


Encrypted S3 buckets are currently not supported.

Upgrade a Private Supermarket

  1. Shut down the server running Private Supermarket.

  2. Backup the /var/opt/supermarket directory.

  3. Download the correct package of Chef Supermarket for your operating system from Chef Downloads.

  4. Upgrade your system with the new package using the appropriate package manager for your distribution:

    • For Ubuntu:

      dpkg -i /path/to/package/supermarket*.deb
    • For RHEL / CentOS:

      rpm -Uvh /path/to/package/supermarket*.rpm
  5. Reconfigure the server that Chef Supermarket is installed on:

    sudo supermarket-ctl reconfigure

Private Supermarket is updated on your server now. We recommend restarting the services that run Chef Supermarket to ensure that the old installation of Chef Supermarket doesn’t persist in the server memory.

  1. Get the name of the active unit:

    systemctl list-units | grep runsvdir
  2. Restart the unit:

    systemctl restart UNIT_NAME

    This will restart the runsvdir, runsv, and svlogd service processes that run Chef Supermarket.
