Prevent OOM inside container - kubernetes

I'm running conda install -c anaconda pycodestyle in a container with this spec:
apiVersion: v1
kind: Pod
metadata:
name: conda-${PYTHON_VERSION}
spec:
securityContext:
runAsUser: 0
runAsGroup: 0
containers:
- name: python
image: continuumio/conda-ci-linux-64-python${PYTHON_VERSION}
command:
- /bin/bash
args:
- "-c"
- "sleep 99d"
workingDir: /home/jenkins/agent
resources:
requests:
memory: "256Mi"
cpu: "1"
limits:
memory: "256Mi"
cpu: "1"
My understanding was that if I set limits and requests to the same value, OOM won't be called... seems like I was wrong.
To make myself clear: I don't want overprovisioning to happen at all, I don't want the kernel to panic, if it allocated memory it cannot back up with real memory.
Ideally, I want to understand how to prevent these errors from happening in Kubernetes at all, not specifically for conda, but if there's any way to limit conda to a particular amount of memory, it'll help too.
The machine running these containers has 16MB of memory, and it might, at most, try to run three of those.
The OMM message looks like this:

I also don't like the word "burstable" here... I thought it was supposed to be "guaranteed"

I am having a problem with the output of this code:
#!/usr/bin/perl
# Opening the file timelog.txt, the "<" indicates that the file is being opened in read mode
open(DATA, "<timelog.txt") or die "Couldn't open file timelog.txt, $!";
# Looping through each line in this file, this each line can be accesed with $_
while(<DATA>) {
# In the line ($_), we search for patters
# We first search the pattern " pts/"
$_ =~ m/ pts\//;
# We store the text before this pattern in the variable userId
$userId = "$`";
# We now search for the patter "Word Number Number:Number - Number:Number"
# This pattern is found at the end of each string
$_ =~ m/(\w+) (\d+) (\d+):(\d+) - (\d+):(\d+)/;
# The required variables, i.e. the month start hour, start minutes, end hour and end minutes are extracted
($month, $hours1, $minutes1, $hours2, $minutes2) = ($1, $3, $4, $5, $6);
# $userId." ".$month is used to concatenate the userId along with month with a space between them
# the . is used to concatenate
# If the key already exists, we increase the value of time
if(exists($store{$userId." ".$month})){
$store{$userId." ".$month} += (($hours2 - $hours1)*60) + $minutes2 - $minutes1;
} else {
# If the key does not exist we create a new key value pair
$store{$userId." ".$month} = (($hours2 - $hours1)*60) + $minutes2 - $minutes1;
}
# Note that the key is concatenation of userId and the month
}
# We now loop through the elements and print them
foreach $key (keys %store){
print "$key $store{$key} minutes\n";
}

I do not know why I am getting 3 outputs for each user (each should be just 2) being the third one an empty one.

Please make a small change to your code for debug purpose:
at very begin add
use strict;
use warnings;
and output your captured data
# The required variables, i.e. the month start hour, start minutes, end hour and end minutes are extracted
my ($month, $hours1, $minutes1, $hours2, $minutes2) = ($1, $3, $4, $5, $6);
my $format = "DEBUG: %-25s %3s %02d:%02d %02d:%02d\n";
printf $format,$userId, $month, $hours1, $minutes1, $hours2, $minutes2;
# $userId." ".$month is used to concatenate the userId along with month with a space between them
Debug information gives you a clue where the problem is originated from and you will figure out the direction how to correct it.
NOTE: your code is flowed as it does not take into an account when login crosses midnight hour -- computation will get negative time
The code after a slight modification could look like following (midnight issue still present)
use strict;
use warnings;
use feature 'say';
my $fname = shift || 'timelog.txt';
my %store;
my $re = qr|(\w+)\s+pts/\d\s+(.*?)\s+\w{3} (\w{3}) (\d+) (\d+):(\d+) - (\d+):(\d+)|;
# Opening the file timelog.txt, the "<" indicates that the file is being opened in read mode
open(DATA, '<', $fname)
or die "Couldn't open file timelog.txt, $!";
while(<DATA>) {
next unless /$re/;
my($userId,$host,$month,$hours1,$minutes1,$hours2,$minutes2) = ($1,$2,$3,$4,$5,$6,$7);
# $userId." ".$month is used to concatenate the userId along with month with a space between them
# the . is used to concatenate
# If the key already exists, we increase the value of time
if(exists($store{$userId." ".$month})){
$store{$userId." ".$month} += (($hours2 - $hours1)*60) + $minutes2 - $minutes1;
} else {
# If the key does not exist we create a new key value pair
$store{$userId." ".$month} = (($hours2 - $hours1)*60) + $minutes2 - $minutes1;
}
# Note that the key is concatenation of userId and the month
}
# We now loop through the elements and print them
foreach my $key (sort keys %store){
printf "%-25s - %6d minutes\n", $key, $store{$key};
}

code-oss (Code - OSS) on FreeBSD-CURRENT: renderer process crashing, the application can no longer open my workspace

FreeBSD editors/vscode recently began crashing for me at startup.
Removed, reinstalled, no improvement.
I wondered whether removal of rapid_render.json would work around the issue, it did not.
Another user of the system can start the application without crashing.
Please: how might I resolve the issue?

– unfortunately, nothing useful in the backtrace.

Bug reported:
Code - OSS crashed consistently at start time – renderer process crashed! – until after I removed cached data workbench.desktop.main-17c1ea9255cc303c9339b9c2ce2b4a02.code · Issue #113069 · microsoft/vscode
With the bugged ~/.config/Code - OSS directory (restored from a backup):
After removing the offending file, a first run of the application:
Extension host terminated unexpectedly.
This occurred a few seconds after every run of the application.
Output from code-oss --verbose at https://pastebin.com/gPXMNdrv
After disabling all possible extensions (English (United Kingdom) Language Pack for Visual Studio Code can not be disabled), then re-enabling all: touch wood, no recurrence of Extension host terminated unexpectedly.

Mongod service crashed after performing mongodump

I performed this query
query: mongodump --db=elastic --collection=q_moonx_notifications_2019-08-26 --out=/home/centos/mongo-dump/
on my mongo db to take a dump of one collection which is around
Collection name: q_moonx_notifications_2019-08-26
size : 80GB
storageSize : 23.6GB
Soon after doing this, mongod service crashed.
I went through /var/log/messages to find the problem.
I got to know it happened due to 'out-of-memory' issue.
Can someone help me how it happened and how can I take a dump of a single collection without effecting my running mongo service.
Machine has 32 gb memory and 0 swp.

You ran into a "problem" called the "OOM-Killer".
A quote from the part of the MongoDB documentation aptly named Production notes:
Swap
Assign swap space for your systems. Allocating swap space can avoid issues with memory contention and can prevent the OOM Killer on Linux systems from killing mongod.
For the WiredTiger storage engine, given sufficient memory pressure, WiredTiger may store data in swap space.
(emphasis by me)
What basically happened is that the memory pressure on the system became critical, and the kernel decided to kill a process to free some RAM in order to ensure the system can still run. It does so by determining the "badness" of a task via
badness_for_task = total_vm_for_task / (sqrt(cpu_time_in_seconds) *
sqrt(sqrt(cpu_time_in_minutes)))
and killing the baddest task. See https://www.kernel.org/doc/gorman/html/understand/understand016.html
for details.
Gist: MongoDB presumably consumes several orders of magnitude more RAM than any other process on the server, hence it get's killed by the OOM Killer when the Kernel has no option to swap out some data and thereby ensure the basic system tasks still can run.
This behaviour can basically be prevented by allocating swap, which is why it is accordingly documented in the production notes.

From the official document -
mongodump reads data from a MongoDB database and creates high fidelity BSON files which the mongorestore tool can use to populate a MongoDB database. mongodump and mongorestore are simple and efficient tools for backing up and restoring small MongoDB deployments, but are not ideal for capturing backups of larger systems.
When connected to a MongoDB instance, mongodump can adversely affect mongod performance. If your data is larger than system memory, the queries will push the working set out of memory, causing page faults.
and for the above said result it is important to have swap memory ready for using these commands.
I would suggest to create swap memory as a first step you can check the required steps for your specific os you are using. This is the best I can recommend for creating swap space.
If that doesn't help please increase the memory.

How to install PGlogical from sources on Freebsd?

I have Postgresql 9.5 server on Freebsd. I try to install PGlogical (http://2ndquadrant.com/en/resources/pglogical/) from sources. But when I downloaded tarball and unpacked it, I saw only these files:

And I didn't see configure file and other. How to install this tarball? OS - Freebsd 10.2

You can install pglogical from sources only using PostgreSQL sources:
Download sources of PostgreSQL of necessary version.
You also need pglogical_output extension and its sources. You can read about it in the documentation. Download it from GitHub.
Configure PostgreSQL. More about it in the documentation.
Copy downloaded sources of pglogical and pglogical_output to directories contrib/pglogical and contrib/pglogical_output.
Execute commands:
cd <path-to-postgres-sources>/contrib/pglogical
make install
cd <path-to-postgres-sources>/contrib/pglogical_output
make install
Read the documentation to setup pglogical.

Did you read the README file? It will probably tell you to use make, as there is a Makefile

Any help,thanks a lot!

One way using find:
find . -maxdepth 1 -type f -name "*.java" -newermt 2012-10-16 ! -newermt 2012-10-18 -exec cp '{}' /home/user/dstFolder/ \;

You can use xargs to copy the files found:
...| xargs -i cp '{}' /home/user/dstFolder/
This will copy all the files found to the folder /home/user/dstFolder/.
