json-env

A tool to read and modify Base64 encoded JSON to use configurations JSON-files for CI/CD environments.

To install

Go has to be installed.

go get github.com/palchukovsky/json-env

Examples

Set value

json-env -source eyJmIjoidmFsMiIsIngiOnsieSI6eyJ6IjoidmFsMSJ9fX0 -write "x/y/z=1 2 3" z=valX

Read value

json-env -source eyJmIjoidmFsMiIsIngiOnsieSI6eyJ6IjoiMSAyIDMifX0sInoiOiJ2YWxYIn0 -read x/y/z
json-env -source eyJmIjoidmFsMiIsIngiOnsieSI6eyJ6IjoiMSAyIDMifX0sInoiOiJ2YWxYIn0 -read z
json-env -source eyJmIjoidmFsMiIsIngiOnsieSI6eyJ6IjoiMSAyIDMifX0sInoiOiJ2YWxYIn0 -read zz -default "is not existent"

Export source

json-env -source eyJmIjoidmFsMiIsIngiOnsieSI6eyJ6IjoiMSAyIDMifX0sInoiOiJ2YWxYIn0 -export

Encode JSON-file to Base64

json-env -encode_file /path/config.json

Use-case example

CONFIG ?= $(shell json-env -encode_file ./.config.json)
AWS_APP_GATEWAY_ID := $(shell json-env -source ${CONFIG} -read service/aws/gateway/app/id)
AWS_REGION := $(shell json-env -source ${CONFIG} -read service/aws/region)
CONFIG := $(shell json-env -source ${CONFIG} -write \
    "build/version=${VERSION}" \
    "build/commit=${COMMIT}" \
    "build/id=${BUILD}" \
    "build/builder=${BUILDER}" \
    "build/maintainer=${MAINTAINER}" \
    "service/aws/gateway/app/endpoint=${AWS_APP_GATEWAY_ID}.execute-api.${AWS_REGION}.amazonaws.com/${VERSION}")
AWS_ACCESS_KEY_ID := $(shell json-env -source ${CONFIG} -read builder/aws/accessKey/id)
AWS_SECRET_ACCESS_KEY := $(shell json-env -source ${CONFIG} -read builder/aws/accessKey/secret)
AWS_ACCOUNT_ID := $(shell json-env -source ${CONFIG} -read service/aws/accountId)
AWS_AUTH_GATEWAY_ID := $(shell json-env -source ${CONFIG} -read service/aws/gateway/auth/id)
    
define create-config-file
    -mkdir -p ${1}
    @echo "json-env -source CONFIG -export > ${1}lambda_config.json"
    @json-env -source ${CONFIG} -export > "${1}lambda_config.json"
