Ansible playbook exiting without giving proper error message - centos

I'm facing an issue with an Ansible playbook. Ansible is exiting without giving any proper error message. Here is my code:
- name: Installing dependencies
yum: pkg={{ item }} state=latest
with_items:
- gtk+-devel
- gtk2-devel
I wanted to install above packages in my CentOS7. I'm able to install it manually by giving the command sudo yum install gtk+-devel gtk2-devel. But Ansible is throwing the below message and exiting from execution:
TASK [server : Installing dependencies] ****************************
ok: [localhost] => (item=[u'gtk+-devel', u'gtk2-devel'])
NO MORE HOSTS LEFT *************************************************************
to retry, use: --limit #/Users/rolindroy/ansible/setup.retry
PLAY RECAP *********************************************************************
localhost : ok=2 changed=1 unreachable=0 failed=1
Ansible version: 2.1.2.0
EDIT:
Running the playbook with the -vvv option yields this error (but I'm able to install it manually):
failed: [localhost] (item=[u'gtk+-devel', u'gtk2-devel']) => {"changed": false, "failed": true, "invocation": {"module_args": {"conf_file": null, "disable_gpg_check": false, "disablerepo": null, "enablerepo": null, "exclude": null, "install_repoquery": true, "list": null, "name": ["gtk+-devel", "gtk2-devel"], "state": "latest", "update_cache": false, "validate_certs": true}, "module_name": "yum"}, "item": ["gtk+-devel", "gtk2-devel"], "msg": "No Package matching 'gtk+-devel' found available, installed or updated", "rc": 0, "results": []}

Ansible fails with runuser: command not found

I am trying to provision a PostgreSQL server using role galaxyproject.postgresql. Using Vagrant box generic/centos7 this role fails with message
TASK [galaxyproject.postgresql : Initialize database (RedHat >= 7)] ************
fatal: [postgresql]: FAILED! => {"changed": true, "cmd": ["/usr/pgsql-9.6/bin/postgresql96-setup", "initdb"], "delta": "0:00:00.181409", "end": "2019-10-16 01:45:59.495713", "msg": "non-zero return code", "rc": 1, "start": "2019-10-16 01:45:59.314304", "stderr": "", "stderr_lines": [], "stdout": "Initializing database ... failed, see /var/lib/pgsql/9.6/initdb.log", "stdout_lines": ["Initializing database ... failed, see /var/lib/pgsql/9.6/initdb.log"]}
The file /var/lib/pgsql/9.6/initdb.log has the following message
/usr/pgsql-9.6/bin/postgresql96-setup: line 143: runuser: command not found
On the target node runuser is available
[root#postgresql ~]# which runuser
/sbin/runuser
So the problem seems to be that /sbin is not on the PATH when Ansible runs on target nodes.
How can I make runuser command available to Ansible? I don't want to change the external role galaxyproject.postgresql of course.
When I output PATH using Ansible debug it shows that PATH does not include sbin.
TASK [galaxyproject.postgresql : debug] ****************************************
ok: [postgresql] => {
"PATH": {
"changed": true,
"cmd": "echo $PATH",
"delta": "0:00:00.010478",

"stderr": "",
"stderr_lines": [],
"stdout": "/usr/local/bin:/usr/bin",
"stdout_lines": [
"/usr/local/bin:/usr/bin"
]
}
}
If you need to add something into PATH, you can try to set environment for this module. I hadn't tried this for postgres module, but it should work:
- postgres_user: # or other module name you are using
user: foo # and other normal arguments
environment:
PATH: '$PATH:/sbin'

Docker,Error: cannot run migrations: database needs bootstrapping;

This is what I have tried
docker run --rm \
> --link kong-database:kong-database \
> -e "KONG_DATABASE=postgres" \
> -e "KONG_PG_HOST=kong-database" \
> kong:latest kong migrations up
But I have
Error: cannot run migrations: database needs bootstrapping; run 'kong migrations bootstrap'
I do not understand what this actually means. If I try
docker run --rm --link kong-database:kong-database -e "KONG_DATABASE=postgres" -e "KONG_PG_HOST=kong-database" kong:latest kong migrations bootstrap
bootstrapping database...
Error: [PostgreSQL error] failed to bootstrap database: ERROR: syntax error at or near "NOT" (150)

How it comes that I need to bootstrap database and why do I have problem?
You have to bootstrap the database before running kong. The up command is deprecated and replaced with bootstrap
Change
kong:latest kong migrations up
To
kong:latest kong migrations bootstrap

Ansible: Failed to reload sysctl: sysctl: cannot stat /proc/sys/net/bridge/bridge-nf-call-iptables: No such file or directory

I'm setting up kubernetes cluster with ansible. I get the following error when trying to enable kernel IP routing:
Failed to reload sysctl: sysctl: cannot stat /proc/sys/net/bridge/bridge-nf-call-iptables: No such file or directory
Is this a bug in ansible or is there something wrong with my playbook?

Ansible failed to complete successfully. Any error output should be
visible above. Please fix these errors and try again.
In the playbook, add the following task to load the br_netfilter module:
- name: Ensure br_netfilter is enabled.
modprobe:
name: br_netfilter
state: present
Loading br_netfilter kernel module fixed the problem. I simply appended it to the ip_modules list in playbook vars declaration. I'm using Centos 7.

Error running postgresql96-setup initdb with Ansible

I am trying to automate the installation of a PostgreSQL database using Ansible.
However, the following task:
- name: Initialize Postgres
command: /usr/pgsql-9.6/bin/postgresql96-setup initdb
become: true
Results in this error:

}
The error in /var/lib/pgsql/9.6/initdb.log is:
/usr/pgsql-9.6/bin/postgresql96-setup: line 140: runuser: command not found
What is interesting is that if I run sudo /usr/pgsql-9.6/bin/postgresql96-setup initdb on the host, it runs successfully...
Any help would be appreciated.
Try with PATH environment variable defined explicitly in the task:
- name: Initialize Postgres
command: /usr/pgsql-9.6/bin/postgresql96-setup initdb
environment:
PATH: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
become: true
Most likely the value of the path is set differently for interactive and non-interactive shell sessions.
Or locate the runuser executable and add the path before running the script:
command: PATH=/runuser/location:${PATH} /usr/pgsql-9.6/bin/postgresql96-setup initdb

EXPOSE 8080
i build it than with:
sudo docker build -t dockerfile .
everything builds fine. so I start the server with:
sudo docker run -it --publish 127.0.0.1:8080:8080 dockerfile:latest
I can see that the server starts correctly
If I enter the URL 127.0.0.1:8080 i got an error site:
the connection was reset - the connection to the server was reset
while the page was loading
How do I get a connection to the server in my browser?

EDIT after jottrs answers:
the logs says:

nothing more....
because of Jottrs IP mention:
As far as i understood, I bind my server to 127.0.0.1:8080 with the start command:
sudo docker run -it --publish 127.0.0.1:8080:8080 dockerfile:latest
If I look with ifconfig i have the docker file running on:
$ ifconfig
docker0 Link encap:Ethernet Hardware Adresse 56:84:7a:fe:97:99

But with $ sudo docker inspect --format "{{ .NetworkSettings.IPAddress }}" 054
i get 172.17.0.5
But I also get no connection in my browser with the URL 172.17.0.5:8080 or URL 172.17.42.1:8080
also if I start with $ sudo docker run -d --publish 172.17.42.1:8080:8080 dockerfile:latest (the ifconfig IP) I will not get a connection (and still no reaction on the logs)
$ sudo docker exec -it 228 bash

The problem is JBoss not Docker. JBoss listen per default only to localhost:8080 Jboss only works on localhost:8080 ,but doesnt reply when called by ip (I'm not a JBoss guy so you have to try "-b 0.0.0.0" or to provide a server.xml via ADD in your Dockerfile).
When you run (in my case I called the container jboss)
sudo docker exec jboss apt-get install curl -y
sudo docker exec jboss curl localhost:8080
you notice that JBoss runs and is accessable.
