Open Source Go Admin Templates

This project provides a convenient way to populate values from Consul into the file system using the consul-template daemon. The daemon consul-template queries a Consul or Vault cluster and updates any number of specified templates on the file system. As an added bonus, it can optionally run arbitrary commands when the update process completes. Please see the examples folder for some scenarios where this functionality might prove useful. While there are multiple ways to run Consul Template, the most common pattern is to run Consul Template as a system service. When Consul Template first starts, it reads any configuration files and templates from disk and loads them into memory. From that point forward, changes to the files on disk do not propagate the running process without a reload.

Hero is a handy, fast and powerful go template engine, which pre-compiles the HTML templtes to go code. It has been used in a production environment in bthub.io. The function definition statement defines the function which represents a html file. The function defined should return one and only one parameter []byte. Extend statement states the parent template the current template extends. Include statement includes a sub-template to the current template. It works like #include in C++. Import statement imports the packages used in the defined function, and it also contains everything that is outside of the defined function. Block statement represents a block. Child template overwrites blocks to extend parent template.

confd is a lightweight configuration management tool focused on keeping local configuration files up-to-date using data stored in etcd, consul, dynamodb, redis, vault, zookeeper, aws ssm parameter store or env vars and processing template resources. confd is also focused on reloading applications to pick up new config file changes. Go 1.10 is required to build confd, which uses the new vendor directory. You should have a working etcd, or consul server up and running and the ability to add new keys. Template resources are defined in TOML config files under the confdir. confd supports two modes of operation daemon and onetime. In daemon mode confd polls a backend for changes and updates destination configuration files if necessary. The metadata api prefix can be defined on the cli, or as part of your keys in the template toml file.

pongo2 is a Django-syntax like templating-language for Go. The latest version is 6.0.0. Official additional filters/tags for pongo2 (for example a markdown-filter). They are in their own repository because they’re relying on 3rd-party-libraries. Most major Go web frameworks tightly integrated with our template engine pongo2. Fortune 500 companies and popular projects are using pongo2. Our template engine pongo2 is free to use for private & commercial products and licensed unter the MIT license. Please contact us if you’re using pongo2 to have you added to the list of users. We offer free, low priority support in our GitHub issue tracker and commercial prioritized support (such as consulting, private feature development and paid bug fixing).

Template and patch as needed to easily make your configuration reusable and extensible. Works with your own and third-party YAML configuration. ytt templates are plain YAML documents made from nodes such as maps and arrays. ytt allows you to set values and attach statements (such as if and for loops) on those nodes. This eliminates text insertion concerns like manual escaping and allows for easy structure reuse, thus, increasing readability. Weave ytt templating into your own configuration, externalize values to variables, extract repeated snippets to functions, and make whole sections conditional. Patch on top of any configuration using ytt overlays. Express precise structural edits and invariant declaratively. ytt execution environment is hermetic and side-effect free, with no access to the filesystem, network, time, randomness, or the operating system interfaces. This guarantees that templates produce identical output with the same inputs.
