Github.com ui .currently does not natively supoport search for multiple topic tags as of now. However their api allows you to query multiple tags. Below is a simple example to query github.com with ecs and go topic tags.

curl -H "Accept: application/vnd.github.mercy-preview+json" \
https://api.github.com/search/repositories?q=topic:ecs+topic:go

Response from the github can be rather verbose so lets filter only relavant info such repo url and description.

curl -H "Accept: application/vnd.github.mercy-preview+json" \
https://api.github.com/search/repositories\?q\=topic:ecs+topic:go | jq '.items[] | {url:.url, description:.description}'

Note the following pgrep options are needed:
-a, --list-full           list PID and full command line
-f, --full                use full process name to match
-c, --count               count of matching processes


To find a specific process with a specific commandline parameter use the following:
pgrep -a -f "{processname}.*{commandline param}"

Dynamic Configuration Properties in Spring Boot and Spring Cloud

TL;DR

• Use @ConfigurationProperties and always get state from the bean.
• The Environment can change at runtime and Spring Cloud does this for you using RefreshEvent.
• Changes are propagated to beans in Spring Cloud in 2 ways (@ConfigurationProperties and @RefreshScope).
• If you care about the state of @ConfigurationProperties being consistent on concurrent access, put it or the consumer @Bean in @RefreshScope.
