Una función bash más genérica para exportar vars (con interpolación):
#
#------------------------------------------------------------------------------
# usage example:
# doExportJsonSectionVars cnf/env/dev.env.json '.env.virtual.docker.spark_base'
#------------------------------------------------------------------------------
doExportJsonSectionVars(){
json_file="$1"
shift 1;
test -f "$json_file" || echo "the json_file: $json_file does not exist !!! Nothing to do" && exit 1
section="$1"
test -z "$section" && echo "the section in doExportJsonSectionVars is empty !!! nothing to do !!!" && exit 1
shift 1;
while read -r l ; do
eval $l ;
done < <(cat "$json_file"| jq -r "$section"'|keys_unsorted[] as $key|"export \($key)=\(.[$key])"')
}
datos de ejemplo
cat cnf/env/dev.env.json
{
"env": {
"ENV_TYPE": "dev",
"physical": {
"var_name": "var_value"
},
"virtual": {
"docker": {
"spark_base": {
"SPARK_HOME": "/opt/spark"
, "SPARK_CONF": "$SPARK_HOME/conf"
}
, "spark_master": {
"var_name": "var_value"
}
, "spark_worker": {
"var_name": "var_value"
}
}
, "var_name": "var_value"
}
}
}
keys
ordena las claves, por lo que vale la pena señalar quekeys_unsorted
no.
