toml_update

Update a toml configuration file from ENV variables

Example

This example uses a telegraf configuration file, same works for other projects using the same configuration format

docker run --rm telegraf telegraf config > test.conf
export CONF_UPDATE=test.conf
export CONF_PREFIX=PFX

export PFX_myvar1=inputs.cpu.totalcpu=false
export PFX_whatever2=agent.interval="20s"
export PFX_ping_urls=inputs.ping.urls=["google.com","amazon.com"]
export PFX_emptysection=inputs.netstat.enabled=#no configuration

grep -e 'totalcpu' -e '^[^#]*interval = ' test.conf
# if you've cloned the repo, simply run `go build toml_update.go` to get the binary
./toml_update
grep -e 'totalcpu' -e '^[^#]*interval = ' test.conf
