TeaChart

TeaChart is a tool for managing docker containers like Helm Chart. As usual, we use docker compose to manage our docker containers. But for some big systems which have lots of containers, we devote our energy in maintaining config files. Then TeaChart can help to do this. TeaChart uses Helm Chart's render engine to generate config files automatically. This project is WIP. May have breaking changes in the future.

Install

As project is WIP, so binary releases will not be provided now. We recommend you using Dev Container, then there's no need to prepare the build enviroment.

Then run the command below in terminal to build the binary.

make build

At last, you can add the binary teachart to your PATH, then you are ready to go.

Usage

For user

First, you need to add a repository. All repositories are managed by go-git. They will be all saved in repos folder under the binary install folder.

# add teachart repository, NAME will be the folder name. 
# So disallowed charactors in folder name, can not be used here
teachart repo add REPO_NAME https://github.com/xxx/xxx
# if the repo folder already exists, you can add --force/-f flag to overwirte it.
teachart repo add REPO_NAME https://github.com/xxx/xxx -f

Then you can install the added chart repo. But before do that, you should notice that there are many changeable values in a chart. All of them have default values. For most of the time, the default values should be overwirted. For example, the database username and password. So if necessary, you can edit your own values.yaml. And pass it by using --values/-f flag as following.

teachart install REPO_NAME -f PATH_TO_VALUES_YAML

Sometimes, chart may not provide changeable values. You can use --set flag to change the docker compose config file, what ever you want.

teachart install REPO_NAME --set xxx.xxx.xxx=xxx

After the installation, teachart will generate docker compose yaml files in .teachart under the work directory. Ensure not deleting .teachart folder, as it will be used when uninstall the chart. You can uninstall the chart by the following command.

teachart uninstall

You can use -h flag to check more optional flags which are not mentioned here.

For Chart developer

As we use Helm's engine, you can use all features from Helm.

But .Chart is overrided to .TeaChart, and not all values are avaliable in .TeaChart.
