Mirror Ubuntu mirror in corporate Artifactory

 

Configuring Artifactory using remote repository, selecting the generic 

Provide the url of the repository you wan to mirror, select the type generic. 

In case you are behind a proxy you may select it. 

     

Go on the Linux machine that you want to use this mirror and edit file /etc/apt/sources.list

Change the default location from archive.ubuntu.com to your internal mirror.

That's it

Docker campaign

My notes to startup docker:

Configure your internal docker repository

Find your internal Trusted Repository
dtr.mycompany.com

In your : /etc/docker/daemon.json file

Make sure that you trust your repository:
{
    "insecure-registries" : ["dtr.mycompany.com"]
}

curl -k https://dtr.mycompany.com/ca -o /usr/local/share/ca-certificates/dtr.mycompany.com.crt

update-ca-certificates

service docker restart

Allow the user (not root to use docker)

usermod -aG docker myuser
su - myuser
newgrp

Create a docker file

Create the docker file

FROM  dtr.mycompany.com/mycompany/httpd:latest
LABEL maintainer="clement_soullard@infosys.com"
EXPOSE 80
COPY dist/ui  /usr/local/apache2/htdocs/
COPY docker/certs/server.crt /usr/local/apache2/conf/
COPY docker/certs/server.key /usr/local/apache2/conf/
COPY docker/httpd.conf /usr/local/apache2/conf/httpd.conf
RUN sed -i \
        -e 's/^#\(Include .*httpd-ssl.conf\)/\1/' \
        -e 's/^#\(LoadModule .*mod_ssl.so\)/\1/' \
        -e 's/^#\(LoadModule .*mod_socache_shmcb.so\)/\1/' \
        conf/httpd.conf

Useful commands

Stopping a container

docker stop specworks-ui

Removing a container

docker rm specworks-ui

docker image build -t specworks-ui:1.0 .
docker container run --publish 8000:80 --detach --name specworks-ui specworks-ui:1.0
docker exec -it specworks-ui  bash

docker network create -d bridge specworks-net

cp commands works recursively

docker cp docker/httpd.conf specworks-ui:/usr/local/apache2/conf/httpd.conf

Clean up the docker cache

docker system prune -a -f 

Download image from proxy 

mkdir /etc/systemd/system/docker.service.d

Now create a file called /etc/systemd/system/docker.service.d/http-proxy.conf that adds the HTTP_PROXY environment variable:

[Service]
Environment="HTTP_PROXY=http://proxy.example.com:80/"

If you have internal Docker registries that you need to contact without proxying you can specify them via the NO_PROXY environment variable:

Environment="HTTP_PROXY=http://proxy.example.com:80/"
Environment="NO_PROXY=localhost,127.0.0.0/8,docker-registry.somecorporation.com"

Flush changes:

$ sudo systemctl daemon-reload

Verify that the configuration has been loaded:

$ sudo systemctl show --property Environment docker
Environment=HTTP_PROXY=http://proxy.example.com:80/

Restart Docker:

$ sudo systemctl restart docker

 

Managing entries/password in LDAP from command line

First you have to install the utilities of openLDAP to connect to your LDAP. LDAP is a protocol, it means that you can use the openldap library to connect to other ldap like apache ds for instance:

yum install openldap-clients.x86_64

You can change the password using the admin bind account



ldappasswd -H ldap://:10399 -x -D "uid=admin,ou=system" -W -S "uid=bhashya_avula,ou=Persons,dc=mycompany,dc=com"



Or you can use the user account to change the password

ldappasswd -H ldap://:10399 -x -D "uid=xcvvsd,ou=Persons,dc=,dc=com" -W -A -S

If the account is locked, you can unlock it using apache ds. First, make sure that your connection use display the operational information by checking the below box. 


ldapsearch -H ldap://localhost:10389 -b "uid=admin,ou=system" -wXXXXX -s sub "(cn=Soullard)" +

 
















Then remove  the pwdAccountLockedTime attribute
