Commit: 06c469e

Causes in docker-database:

# cat /etc/supervisor/critical_processes
program:redisprogram:redis_bmp

Due to:

$ cat ./dockers/docker-database/critical_processes.j2 
{% if INSTANCES %}
{%     for redis_inst, redis_items in INSTANCES.items() %}
program:{{ redis_inst }}
{%-     endfor %}
{%- endif %}

LF removal by {%- ...}

Suggested fix:

{% if INSTANCES -%}
{%     for redis_inst, redis_items in INSTANCES.items() -%}
program:{{ redis_inst }}
{%     endfor -%}
{% endif -%}

Example:

$ j2 input.j2 -f json <<< '{"INSTANCES":{"foo":"bar","baz":"..."}}'
program:foo
program:baz
