The documentation and repository aims to: - Provide everything necessary to run the whole Teragrep Cluster and associated components. - Make development and rapid iterations easy for the developers. - Make multiple parallel deployments possible.
The user is expected to have Helm and supported version of Kubernetes cluster installed with basic know-how how to operate them.
Tested on Minikube with KVM2 driver.
The config.yaml values file contains all "meta" and shareable configuration lines and is needed by Helm.
The shareable module contains all shareable configuration files.
The application-specific configurations for all modules can be found inside ${MODULE}/config directories.
All helm related files can be found in directory helm/.
Run ./recreate.sh to create the cluster in correct order. Convenience script, internally uses stop.sh and install.sh scripts.
Run ./stop.sh to destroy the cluster. Convenience script, internally uses uninstall.sh script.
Run ./install.sh module-name to (re-)install a module. Existing installation will be uninstalled first.
Run ./uninstall.sh module-name to uninstall a module.
It is helpful to run kubectl config set-context --current --namespace=teragrep to avoid having to run --namespace teragrep on every step. Alternatively start minikube with --namespace=teragrep argument.
You might need to increase fs.inotify.max_user_instances in case of Failed to create inotify object: Too many open files happening.
The rpm files have to be provided by the user as this repository do not contain them directly. All other files for building container images can be found under dockerfiles directory.
Expected files to be inside dockerfiles/rpms/ directory:
-
ajs_01.rpm -
bos_01.rpm -
hdp_03.rpm -
hdp_04.rpm -
obj-01.rpm -
pth_05.rpm -
pth_10.rpm -
pyz_01.rpm -
rest-01.rpm -
rest-02-backend.rpm -
rest-02-data-tool.rpm -
rest-03-extras.rpm -
spk_02.rpm -
spk_03.rpm -
zep_01.rpm
Read dockerfiles/README.adoc for information.
Be sure to uninstall any running modules to make sure the container images are properly updated.
