I've got a very wierd problem with docker.service. I try to limit memory using that MemoryLimit=8Gbut when I do that containers won't to start after service restart. Other limitatnions which I use works fine:
CPUWeight=60
CPUQuota=80%
IOWeight=20
MemorySwapMax=1

I just upgraded Ubuntu from 18.04 to 22.04 and when I run mvn --version is still see:
Apache Maven 3.6.3
Maven home: /usr/share/maven
Java version: 11.0.15, vendor: Private Build, runtime: /usr/lib/jvm/java-11-openjdk-amd64
Default locale: en, platform encoding: UTF-8
OS name: "linux", version: "5.15.0-1013-aws", arch: "amd64", family: "unix"
which is almost a 2 years old version.
I would like to avoid a manual install and keep using apt to manage the installation of maven. Am I asking for too much or did I miss something?
Running Ubuntu 22.10:
mvn -v

I am trying to use the ansible.builtin.url module to fetch the contents of a remote file on my remote server. I am using one of the examples in the official documentation page of the module, but occasionally I am getting the Name does not resolve error. I am saying occasionally because this behaviour is not consistent. Sometimes I get the results, sometimes I get the error...
How do you suggest I debug this error?
Ansible task
- name: url lookup splits lines by default
debug: msg="{{item}}"
loop: "{{ lookup('url', 'https://ip-ranges.amazonaws.com/ip-ranges.json', wantlist=True) }}"
Playbook output

The problem had to do with the OS version the controller was running. Changing it from alpine:edge to alpine:3.12.1 fixed the problem. This issue helped: https://github.com/gliderlabs/docker-alpine/issues/539
this is my docker details.

after installed ansible on a redhat linux machine(kernel version unknown)
when run ansible-playbook I got such error.
RuntimeError: You are linking against OpenSSL 1.0.0, which is no longer support by the OpenSSL project. You need to upgrade to a newer version of OpenSSL
my python version is: Python 2.7.10
ansible: 2.1.0.0
ssh version: OpenSSH_5.3p1, OpenSSL 1.0.0-fips 29 Mar 2010
I tried upgrade openssl to fix this. But not work.
Finally, I also upgrade openssh, and fix this.
fixed version:
openssl: OpenSSL 1.0.1e-fips 11 Feb 2013
openssh: OpenSSH_6.9p1, OpenSSL 1.0.1e-fips 11 Feb 2013
Hope this will help for you too.
I have recently installed docker in aws ec2 instance by using the command
$ yum install docker
But when I try to run $ docker network --help it says
docker: 'network' is not a docker command.
Please let me know what is the issue here.
Here is the output of docker version
Client version: 1.7.1
Client API version: 1.19
Go version (client): go1.4.2
Git commit (client): 786b29d/1.7.1
OS/Arch (client): linux/amd64
Server version: 1.7.1
Server API version: 1.19
Go version (server): go1.4.2
Git commit (server): 786b29d/1.7.1
OS/Arch (server): linux/amd64
From the docker engine release notes I see in docker 1.9
docker network exits experimental and is part of standard release (#16645)
so docker 1.7.1 seems a bit too old to support docker network.
Amazon Linux AMI has only docker 1.7.1 in its latest release 2015.09, which means it you need and try to install the latest docker yourself.
