Log when cronjobs has started

3

I have a file which contains a bunch of cron jobs:

30 * * * * someexec somefile
30 1 * * * someexec somefile
30 5 * * * someexec somefile

I'd like for when these cron jobs have been activated that something in the fashion of "Cron job someexec somfile has started" to the log file /var/log/cronjobs.log for example.

I do not want to log what these cron jobs echo when they do run as I have already fixed that. I only want to log that the jobs are active.

Startup redis-server then use bash

1

# Redis
    # Download and extract Redis source files
RUN curl -o redis.tar.gz "http://download.redis.io/releases/redis-4.0.2.tar.gz" && \
    mkdir redis_tmp/ && \
    tar xzf redis.tar.gz -C redis_tmp && \
    # Rename temporary directory
    mv redis_tmp/* redis && \
    # Install Redis
    cd redis && \
    make && \
    make install && \
    # Remove source files
    cd .. && \
    rm -rf redis && \
    # Confirm installation
    redis-server -v

# Cleanup
    # Remove local repository package files
RUN apt-get -y clean

ENTRYPOINT redis-server

CMD bash

Here the last part of my Dockerfile. I'd like to run the following command:

docker run -it test_image

I'd like this image to startup redis-server and leave me using bash.

It leaves me with redis-server though:

Webserver in docker container is not reachable via the internet

2

I've been reading: https://docs.docker.com/engine/userguide/networking/#user-defined-networks

I've created my own network (docker network create --driver bridge devils_network):

441be50f3792        bridge              bridge              local
0d73f7c6fe00        devils_network      bridge              local
8e189dda9fef        host                host                local
5ebca4a1e514        none                null                local

I run the container so:

docker run -it -d -v ~/dockervolume/deus:/srv/www --name deus --hostname deus --network=devils_network -p 80:8080 karl/node

And in the dockerfile expose port 8080:

EXPOSE  8080

I've attached a terminal session to the container and inspected the container to make sure the webserver is up and running:

root        17  0.0  0.1   4508   660 ?        S    22:46   0:00 sh -c NODE_PATH="$(pwd)" NODE_ENV=production node hello_world
root        19  0.0  4.3 882896 22004 ?        Sl   22:46   0:00 node hello_world

The webserver is utilizing port 8080 inside the docker container.

I'm running on a DigitalOcean droplet. If I start the server up directly on the host and not via a docker container it works.

How to setup supervisor 3.3.1 with node.js npm scripts

1

I'm running version 3.3.1.

Apart of my /etc/supervisor/supervisord.conf file:

[program:node]
directory=/srv/www
command=npm run demo
autostart=true
autorestart=true

Apart of my package.json file under scripts:

"demo": "npm run prod",
"prod": "NODE_ENV=production NODE_PATH=\"$(pwd)\" node src/index.js"

I attempt to shutdown the node program via supervisorctl, however it persists.

Systemd After not starting service

Description=Renews letsencrypt certificates
After=network.target letsencrypt_concat_fullchain_privkey.service

[Service]
Type=oneshot
WorkingDirectory=/etc/letsencrypt/
ExecStart=/usr/bin/letsencrypt renew

When I start this service manually: sudo systemctl start letsencrypt it doesn't seem to start the letsencrypt_concat_fullchain_privkey.service service. I've ran sudo systemctl start letsencrypt_concat_fullchain_privkey.service and it works as it should.

What I'm trying to do is that when letsencrypt.service is finished I'd like it to start the letsencrypt_concat_fullchain_privkey.service service.

I don't know why it's not resolving?

EDIT, added answer info:

https://docs.docker.com/engine/userguide/networking/#the-default-bridge-network-in-detail:

Docker does not support automatic service discovery on the default bridge network. If you want to communicate with container names in this default bridge network, you must connect the containers via the legacy docker run --link option.

Legacy is pre version 1.10.

Legacy: https://docs.docker.com/engine/userguide/networking/default_network/dockerlinks/

Logstash output-http plugin error 500 when trying to send to slack webhook

3

I'm running a docker container with an ELK stack. Everythings working dandy and fine. I'd like to utilize the https://www.elastic.co/guide/en/logstash/current/plugins-outputs-http.html plugin.

I install the plugin it:

root@elk:/# /opt/logstash/bin/plugin install logstash-output-http
Validating logstash-output-http
Installing logstash-output-http
Installation successful

/etc/logstash/conf.d/logstash.conf main logstash config file:

input {
  beats {
   port => 5044
   type => "logs"
  }
}
filter {
  grok {
    match => { "message" => "\"name\":\"Error\""}
    add_tag => ["error"]
  }
}
output {
  elasticsearch {
    hosts => "localhost:9200"
    sniffing => true
    manage_template => false
    index => "%{[@metadata][beat]}-%{+YYYY.MM.dd}"
    document_type => "%{[@metadata][type]}"
  }
  if "error" in [tags] {
    http {
      http_method => "post"
      url => "https://hooks.slack.com/services/<MY_ID>"
      format => "json"
      content_type => "application/json"
      message => "{\"text\": \"dis is workinz\"}"
    }
  }
}

I've also tried changing the format in the http:

...
format => "message"
...

The configuration is also tested and is valid:

root@elk:/# /opt/logstash/bin/logstash --configtest -f /etc/logstash/conf.d/logstash.conf 
Configuration OK

Both result in it not working. I double checked to make sure the webhook is working with a test (from the logstash docker container):

curl -H "Content-Type: application/json" -X POST -d '{"text":"testing"}' https://hooks.slack.com/services/<MY_ID>

I know tags are being applied properly, checked in Kibana. Also the if clause is also working as I tested putting elasticsearch inside it and it indeed only sent logs with the added error tags to elasticsearch.

Lastly the holy error message from /var/log/logstash/logstah.log:

As you can see it states response_code => 500 internal error. I get the same error with both format => "json" and format => "message".

I'm guessing it has something to do with my configuration (obviously).

File /etc/supervisor/conf.d/supervisord.conf:

[supervisord]
nodaemon=true

[program:rsyslog]
command=service rsyslog start
startsecs=5

I can start up rsyslog manually without any issue with:

service rsyslog start

So as you can see, before I go ahead and start supervisord rsyslog is not running. After I run the supervisord it does indeed start rsyslog however spawns and exits. Anyone know the reason behind this?

Supervisord commands to start rsyslog and haproxy

2

I've been trying to get these two to start when my docker image starts but they never seem to start.

[supervisord]
nodaemon=true

[program:rsyslog]
command=/bin/bash "service rsyslog start"

[program:haproxy]
command=/bin/bash "service haproxy start"

What command is needed to start both in the order of rsyslog first then haproxy?

How to fix simple HAProxy logging

3

I am running Ubuntu 14.04 and I am wondering how I can log everything that happens in HAProxy. I've been reading issues concerning logging and chroot. Everything is telling me to do write different things in different files.

/var/log# ls
alternatives.log  apt  bootstrap.log  btmp  dmesg  dpkg.log  faillog  fsck  lastlog  upstart  wtmp

/etc/rsyslog.d# ls
49-haproxy.conf  50-default.conf

My /etc/haproxy/haproxy.cfg file contains this:

global
    log 127.0.0.1 local0
    maxconn 2048
    tune.ssl.default-dh-param 2048
    stats socket /run/haproxy/admin.sock mode 660 level admin
    stats timeout 30s

    group haproxy

    retries 3

HAProxy reverse proxying with Docker not working

Docker run command, expose port private only

docker run -it -p 8080 myimage /bin/bash

I would expect the code above to expose port 8080 private. However when I run:

docker ps -a

It shows:

0.0.0.0:32770->8080/tcp

How does one set port 8080 to expose only private?

docker pull ubuntu
docker run -d -it ubuntu bash

apt-get install openssh-server -y
exit
docker ps -a 
docker commit <CONTAINER ID> myimg
// tried the following three, same results
docker run -d myimg "/usr/sbin/sshd"

POP3 and IMAP: Setup Gmail & Zoho

2

I wish to use Gmail to handle all of my email needs. Sending, reading, deleting, moving, forwarding etc.. I have a domain with an email at Zoho [email protected], this is working well.

I've always been confused with POP3 and IMAP regarding which server/client does what. Reading What's the difference between POP3 and IMAP for e-mail? hasen't really made me any smarter.

Here is a flow of the email from [email protected] which I would like:

Incoming email(to: [email protected]) -> Zoho inbox([email protected]) -> Gmail account([email protected]) -> Android client/Web browser

I also would like to send:

Android client/Web browser -> Gmail account([email protected]) -> Zoho account([email protected]) -> Send email(from: [email protected])

I would also like to setup so that via Gmail I can send emails via [email protected].

You can say that Gmail is central. How would I set this up? I am guessing it is better to use IMAP as POP3 is old. I would also like to keep copies on Zoho that are not affected by Gmail, so if I delete a message on Gmail that went to [email protected] it would not delete on Zoho (use Zoho as a backup).

What should be the IMAP/POP3 server in this case?

Zoho

POP Configuration details:

Incoming server: pop.zoho.com, Port: 995, SSL
Outgoing server: smtp.zoho.com, Port: 465, SSL

IMAP Configuration details:

Incoming server: imap.zoho.com, Port: 993, SSL
Outgoing server: smtp.zoho.com, Port: 465, SSL

Gmail

Incoming Mail (IMAP) Server - Requires SSL

imap.gmail.com Port: 993 Requires SSL:Yes

Outgoing Mail (SMTP) Server - Requires TLS

smtp.gmail.com Port: 465 or 587 Requires SSL: Yes Requires authentication: Yes Use same settings as incoming mail server

Incoming vs. Outgoing on Zoho

Incoming: Does this mean when Gmail pushes from it's outgoing server to Zohos incoming server?
Outgoing: Zoho to push from its outgoing server to Gmails incoming server?

Incoming vs. Outgoing on Gmail

Incoming: Does this mean from my Android client/web browser to push to Gmails incoming server?
Outgoing: Gmail outgoing server to push to Zohos incoming server?

What do I do in Zoho and what do I do in Gmail?

OpenShift access via terminal (SSH) [Permission denied (publickey,gssapi-keyex,gssapi-with-mic).]

I'm currently sitting on Ubuntu and would like remote access to my application on OpenShift. I have done the following to create a ssh-rsa key (I've replaced the fingerprint with xx:xx...):

> mkdir ~/.ssh
> chmod 700 ~/.ssh
> ssh-keygen -t rsa                                      
Generating public/private rsa key pair.
Enter file in which to save the key (/home/karl/.ssh/id_rsa): openshiftKey
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in openshiftKey.
Your public key has been saved in openshiftKey.pub.
The key fingerprint is:
xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx karl@karllaptop
The key's randomart image is:
+--[ RSA 2048]----+
|                 |
... the rest of the image

This creates two files(notice they are not in ~/.ssh):

~/openshiftKey
~/openshiftKey.pub

I do not know where these files belong, the examples and tutorials say nothing of moving them.

I open the openshiftKey.pub and copy the code:

enter image description here

I paste it into Openshift:

Click save:

Go back to the application settings page and copy the ssh link:

And on my terminal try and connect:

I am sorry as I am new to ssh in this degree, what am I doing wrong?
