----------------------------------
Summary: Add CentOS 8 support to the Docker provisioner
Key: BIGTOP-3356
URL: https://issues.apache.org/jira/browse/BIGTOP-3356
Project: Bigtop
Issue Type: Sub-task
Components: docker, provisioner
Reporter: Kengo Seki
Assignee: Kengo Seki
1. The puppet package provided by puppetlabs installs the puppet command into
/opt/puppetlabs/bin, so we have to append it to the container's PATH
environment variable. Without that, provisioner fails with a "command not
found" error.
2. {{puppet module install}} installs a module to
/etc/puppetlabs/code/environments/production/modules by default in the case of
puppetlabs' one
([https://puppet.com/docs/puppet/5.5/modules_installing.html#concept-5452]). So
we have to add it to the {{--modulepath}} option in docker-hadoop.sh. Without
that, provisioner fails with the following error.
{code:java}
Error: Evaluation Error: Unknown function: 'any2array'. (file:
/bigtop-home/bigtop-deploy/puppet/manifests/bigtop_repo.pp, line: 20, column:
25) on node 31aac35f86a7.bigtop.apache.org
{code}
3. Provisioner copies hiera.yaml to /etc/puppet in the container via
docker-compose, but it's not included in Hiera's lookup path
([https://puppet.com/docs/puppet/5.5/hiera_automatic.html#puppet_lookup]). We
have to specify the {{--hiera_config}} option explicitly when running {{puppet
apply}}. Without that, it fails with the following error.
{code:java}
Error: Function lookup() did not find a value for the name
'bigtop::hadoop_head_node'
{code}
