Accessing Inventory Host Variable In Ansible Playbook

Answer : You are on the right track about hostvars . This magic variable is used to access information about other hosts. hostvars is a hash with inventory hostnames as keys. To access fields of each host, use hostvars['test-1'] , hostvars['test2-1'] , etc. ansible_ssh_host is deprecated in favor of ansible_host since 2.0. So you should first remove "_ssh" from inventory hosts arguments (i.e. to become "ansible_user", "ansible_host", and "ansible_port"), then in your role call it with: {{ hostvars['your_host_group'].ansible_host }} [host_group] host-1 ansible_ssh_host=192.168.0.21 node_name=foo host-2 ansible_ssh_host=192.168.0.22 node_name=bar [host_group:vars] custom_var=asdasdasd You can access host group vars using: {{ hostvars['host_group'].custom_var }} If you need a specific value from specific host, you can use: {{ hostvars[groups['host_group'][0]].node_name }} You should be a

Can't Change The Base Folder For Lite-server In Angular 2 Application

Answer : You should use a file called bs-config.js (instead of a bs-config.json one) since lite-server tries to load a module using the require function. The configuration should be a valid Node module: module.exports = { "port": 8123, "server": { "baseDir": "./src" } }; See this line in the source code: https://github.com/johnpapa/lite-server/blob/master/lib/lite-server.js#L20. This file by default is loaded from the user's project folder. Edit After digging a bit more, the first part of my answer relies on the code from github but not the one actually installed using npm install (version 1.3.4) There are two options in this case: port baseDir Using this command will fix your problem: $ lite-server --baseDir ./src --port 3333 Hope it helps you, Thierry The answer from Thierry Templier is not quite correct (anymore), you can use either the bs-config.json or bs-config.js configuration to adjust your browse

Convert ZonedDateTime To LocalDateTime At Time Zone

Answer : How can I convert it to LocalDateTime at time zone of Switzerland? You can convert the UTC ZonedDateTime into a ZonedDateTime with the time zone of Switzerland, but maintaining the same instant in time, and then get the LocalDateTime out of that, if you need to. I'd be tempted to keep it as a ZonedDateTime unless you need it as a LocalDateTime for some other reason though. ZonedDateTime utcZoned = ZonedDateTime.of(LocalDate.now().atTime(11, 30), ZoneOffset.UTC); ZoneId swissZone = ZoneId.of("Europe/Zurich"); ZonedDateTime swissZoned = utcZoned.withZoneSameInstant(swissZone); LocalDateTime swissLocal = swissZoned.toLocalDateTime(); It helps to understand the difference between LocalDateTime and ZonedDateTime. What you really want is a ZonedDateTime . If you wanted to remove the timezone from the string representation, you would convert it to a LocalDateTime . What you're looking for is: ZonedDateTime swissZonedDateTime = withZoneSameInstant(ZoneId.of

Can I Create View With Parameter In MySQL?

Answer : Actually if you create func: create function p1() returns INTEGER DETERMINISTIC NO SQL return @p1; and view: create view h_parm as select * from sw_hardware_big where unit_id = p1() ; Then you can call a view with a parameter: select s.* from (select @p1:=12 p) parm , h_parm s; I hope it helps. CREATE VIEW MyView AS SELECT Column, Value FROM Table; SELECT Column FROM MyView WHERE Value = 1; Is the proper solution in MySQL, some other SQLs let you define Views more exactly. Note: Unless the View is very complicated, MySQL will optimize this just fine.
