Solid blog entry discussing how to set up Eucalyptus VPC using Midokura

Originally posted on A sysadmin born in the cloud:

About 2 years ago, AWS passed all new account and migrated existing ones to have “EC2 classic” instances into a VPC.

A lot of new features came out from this but most importantly, VPC would provide the ability for everyone to have backend applications running in Private. No public traffic, no access to and from the internet unless wanted. A keystone for AWS to promote the Public cloud as a safe place.

So, Eucalyptus is now taking VPC into the system as one of the key feature for years to come, and have decided to go with Midokura to orchestrate and manage networking.

Midokura is a SDN software which is used to manage routing between instances, to the internet, security groups etc. The super cool thing about about Midokura is its capacity to be high-available and scalable in time. Of course being originally a networking guy, I also find super…

Eucalyptus and CEPH for Elastic Block Storage

Originally posted on A sysadmin born in the cloud:

Today I did my first install of CEPH, which I used as backend system for the Elastic Block Storage (EBS) in Eucalyptus. The advantage of CEPH is that it is a distributed system which is going to provide you replication (persistence for data), redundancy (we are using a pool of resources, not a single target) and scalability : the easiest way to add capacity is to add nodes which will be used for storage, and those nodes can be simple machines.

I won’t go too deep into CEPH installation. The official documentation is quite good for anyone to get up to speed quickly. I personally had no troubles using CentOS7 (el7).
Also, I won’t go too deep into Eucalyptus installation, I will simply share with you the CEPH config files and my NC configuration files which have some values non-indicated in Eucalyptus docs.

I will simply spend some time to configure a…

Deploying the Eucalyptus Management Console on Eucalyptus

More Eucalyptus Cloudformation goodness..this time discussing how to deploy Eucalyptus Management Console. Solid work here!

The Eucalyptus Management Console can be deployed in a variety of ways, but we’d obviously like it to be scalable, highly available and responsive. Last summer, I wrote up the details of deploying the console with Auto Scaling coupled with Elastic Load Balancing. The Cloud Formations service ties this all together by putting all of the details of how to use these services together in one template. This post will describe an example of how you can do this which works well on Eucalyptus (and AWS) and may guide you with your own application as well.

Let’s tackle a fairly simple deployment for the first round. For now, we’ll setup a LaunchConfig, AS group and ELB. We’ll also set up a security group for the AS group and allow access only to the ELB. Finally, we’ll set up a self signed SSL cert for the console. In another post, we’ll add…

EDGE Networking in Eucalyptus

Originally posted on A sysadmin born in the cloud:

We are just about to have Eucalyptus 4.1 released with VPC implementations and some new features, but I think that it is quite important to take a few time to dig into EDGE networking and networking modes in General with Eucalyptus.

For years, we had 3 mainly used modes :

  • MANAGED
    • AWS Security Groups supported and VLANs created to give L2 separation
    • All traffic goes via the Cluster Controller for cross-groups communication
    • Requires a DHCP clean-environment
  • MANAGED-NOVLAN
    • AWS SG supported but no L2 separation
    • All traffic goes via the Cluster Controller for cross-groups communication
    • Requires a DHCP clean environment
  • SYSTEM
    • Customer DHCP server will assign IP addresses to instances
    • No AWS SG compatibility

As we can figure out, if you needed the AWS compatibility you also had to deal with the CC handling all the instances traffic. But the problem is that you also had to dedicate a physical machine to…

The Case for a Policy Decision Point inside the LDAP Server

hspencer77:

Great insight as to the importance of Policy Decision Points with regards to security processes.

Originally posted on iamfortress:

Why on earth would you do that?

We all understand that runtime characteristics change as processes get moved around the network.  Having problems with network io?  Move the database daemon to the same tier as the client process.  Problems with file io?  Store the data in memory as opposed to disk.  etc…

These same techniques apply for system architecture and security.  Location of policy enforcement, decision, and database processes hugely impact the overall welfare of your organization’s computational systems.

With these kinds of thoughts, what happens when security processes get moved around the network?

But first, we must define the security processes:

1. Policy Enforcement Point (PEP)

The gatekeeper component.  It enforces the security policy on the client program.  PEPs come in many shapes and sizes.  Often times it’s a small block of code that gets embedded directly into a client program.

2. Database (DB)

The database is used by PDPs to house…

Adding Eucalyptus Load Balancer Access Logging for Eucalyptus Cloud Users

Preface

Eucalyptus continues to strive as the best on-premise AWS-compatible Infrastructure as a Service (IaaS).  One of the great things about Eucalyptus being an open source platform, is that if there is an AWS feature that any cloud administrator/developer wants to add, they have the ability to do it.  This blog entry will cover how to enable cloud users to have access to the Eucalyptus Load Balancer access logs – similar to how this is accomplished with Amazon Web Services Elastic Load Balancer service.

Before we dive in, I would like to give special thanks to the following members of the Eucalyptus Engineering Team.  Without their hard work, this blog would not be possible:

Special thanks to these individuals for their continued contributions to the Eucalyptus software.

Overview

Currently, when a cloud user launches a Eucalyptus Load Balancer, they will see something similar to the following:

# eulb-create-lb hasp-euca-lb --listener "lb-port=80, protocol=http, instance-port=8888, instance-protocol=http" --availability-zone Honest
# eulb-describe-lbs
LOAD_BALANCER hasp-euca-elb hasp-euca-elb-325271821652.eulb.future.euca-hasp.cs.prc.eucalyptus-systems.com 2014-12-11T23:34:35.397Z

Notice the DNS name of the load balancer.  It has the following format:

{load balancer name}-{Account ID}.{Load Balancer DNS Subdomain}.{Eucalyptus Cloud DNS Domain}

The “{load balancer name}-{Account ID}” string is the important information in this value.

From the cloud administrator’s perspective, the load balancer is an AutoScaling group.  More information can be found in the following resources:

If the cloud administrator describes the instances running under the ‘eucalyptus‘ account and the load balancer above is running, the following would be displayed:

# euca-describe-instances 
RESERVATION r-278c161e 094999295155 euca-internal-325271821652-hasp-euca-elb
INSTANCE i-135b4b0a emi-7a4367b8 euca-10-104-7-21.future.future.euca-hasp.cs.prc.eucalyptus-systems.com euca-172-17-156-121.future.internal running euca-elb 0 c1.medium 2014-12-11T23:34:44.428Z Honest monitoring-enabled 10.104.7.21 172.17.156.121 instance-store hvm c4946e25-64ed-4453-808c-9ff2ab831b47_Honest_1 sg-da911c98 arn:aws:iam::094999295155:instance-profile/internal/loadbalancer/loadbalancer-vm-325271821652-hasp-euca-elb x86_64

TAG instance i-135b4b0a euca:node 10.104.1.218

Notice the ‘RESERVATION’ line that contains the security group that the instance is using.  If the ‘euca-internal-‘ prefix is removed, the security group has the following format:

{Account ID}-{load balancer Name}

This information matches the Load Balancer launched by the cloud user and will be the base for the solution.

Building the Foundation

In order to get started, the solution needs to be applied from the Cloud Administrator (i.e. admin user in the ‘eucalyptus’ account) perspective.  This solution can not be applied by any other type of cloud user.  In addition to cloud administrator user requirement, the following is needed:

Once these requirements are met, the environment is ready to go.

Create ELB Access Log User

A user (e.g. ‘elb-osg-logger’) needs to be created under the ‘eucalyptus’ account which will be used with the custom python script to store the load balancer access logs to the OSG bucket.  To create the user, after sourcing the cloud administrator credentials, use euare-usercreate:

# euare-usercreate -u elb-osg-logger -k 
AKILXXXXXXXXXXXXXX
PS6nXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

Store these credentials in a safe place.  Next, customizing the load balancer instance.

Customize the Load Balancer

To begin, a Eucalyptus Load Balancer needs to be launched in order to modify it.  The goal here is to build an image from this instance using euca-bundle-instance.  We will start with the load balancer mentioned earlier:

# euca-describe-instances 
RESERVATION r-5e1d4d17 094999295155 euca-internal-325271821652-hasp-euca-lb
INSTANCE i-315dd646 emi-7a4367b8 euca-10-104-7-9.future.future.euca-hasp.cs.prc.eucalyptus-systems.com euca-172-17-177-235.future.internal running euca-elb 0 c1.medium 2014-12-11T04:23:04.441Z Honest monitoring-enabled 10.104.7.9 172.17.177.235 instance-store hvm b134a0bc-cfc4-4c6e-84ba-4fd1df160407_Honest_1 sg-b6cc605e arn:aws:iam::094999295155:instance-profile/internal/loadbalancer/loadbalancer-vm-325271821652-hasp-euca-lb x86_64

TAG instance i-315dd646 euca:node 10.104.1.218

To access the load balancer, authorize SSH to the instance:

# euca-authorize -P tcp -p 22 euca-internal-325271821652-hasp-euca-elb

Next, SSH into the ELB instance:

# ssh -i euca-elb.priv root@euca-10-104-7-9.future.future.euca-hasp.cs.prc.eucalyptus-systems.com

Once inside the instance, install the EPEL package repository:

# yum localinstall --nogpgcheck https://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm -y

After the package has been installed, use yum to install the python-pip package:

# yum install python-pip -y

Next, use pip to upgrade and install the ‘boto‘ and ‘argparse‘ modules:

# pip install --upgrade boto argparse

Now, its time to add the custom python script.

Add Access Logs Script

The Access Log Script performs the following actions:

  • Creates a bucket with READ bucket ACL for Account  ID which launches the Eucalyptus Load Balancer
    • bucket created with the following format – s3://access_logs-{LB name}_{public-IPV4 of LB}_{LB instance numeric ID}
  • Places a copy of “/var/log/load-balancer-access.log.1” in the bucket with READ object ACL for Account ID which owns the Eucalyptus Load Balancer
    • the file in the bucket will have the following naming format – elb-access-{timestamp DDMMYY-HourMinSec}.log
  • Bonus – since Eucalyptus 4.0.0, OSG has supported object lifecycle management.  If lifecycle value is passed and its greater than 0, the object lifecycle is applied to all objects in the bucket.

To add the script to the instance, use curl:

# curl http://euca-elb-access-log-blog.s3.amazonaws.com/access-log-transfer-s3.py -o access-log-transfer-s3.py

Once the script has been downloaded, edit the script and add the ‘elb-osg-logger’ user credentials, the S3_URL and EC2_URL to the script in the following locations:

 EC2Connection.DefaultRegionEndpoint = '<EC2_URL - Eucalyptus Cloud Compute API DNS Name>'
 ec2conn = EC2Connection(aws_access_key_id="<elb-osg-logger user Access Key ID>",
 aws_secret_access_key="<elb-osg-logger user Secret Access Key>",
 is_secure=False, port="8773")
 s3 = S3Connection(aws_access_key_id="<elb-osg-logger user Access Key ID>",
 aws_secret_access_key="<elb-osg-logger user Secret Access Key>",
 host="<S3_URL - Eucalyptus Cloud OSG API DNS Name>",
 is_secure=False, port=8773, calling_format=OrdinaryCallingFormat())

Set the script to be executable using chmod:

# chmod a+x /root/access-log-transfer-s3.py

Now its time to configure HAProxy to log information.

Enable HAProxy Logging

The Eucalyptus Load Balancer uses haproxy to perform load balancing.  To enable logging, the following files need to be edited:

  • /etc/load-balancer-servo/haproxy_template.conf 
    • under the ‘global’ section add – log 127.0.0.1 local3 info
    • under the ‘default’ section add – log global
  • /usr/lib/python2.6/site-packages/servo/haproxy/haproxy_conf.py
    • change the following section:
 if protocol == 'http' or protocol == 'https':
 self.__content_map[section_name].append('log-format httplog\ %f\ %b\ %s\ %ST\ %ts\ %Tq\ %Tw\ %Tc\ %Tr\ %Tt') 
 elif protocol == 'tcp' or protocol == 'ssl':
 self.__content_map[section_name].append('log-format tcplog\ %f\ %b\ %s\ %ts\ %Tw\ %Tc\ %Tt')

to

if protocol == 'http' or protocol == 'https':
 self.__content_map[section_name].append('log-format httplog\ %f\ %b\ %s\ %ST\ %ts\ %Tq\ %Tw\ %Tc\ %Tr\ %Tt\ %{+Q}r\ %ci:%cp\ %fi:%fp\ %si:%sp\ req_size=%U\ resp_size=%B')
 elif protocol == 'tcp' or protocol == 'ssl':
 self.__content_map[section_name].append('log-format tcplog\ %f\ %b\ %s\ %ts\ %Tw\ %Tc\ %Tt\ %{+Q}r\ %ci:%cp\ %fi:%fp\ %si:%sp\ req_size=%U\ resp_size=%B')

For more information about the log-format in HAProxy, reference the HAProxy documentation on log format. The information that can be logged is highly customizable.  Reference the AWS ELB documentation regarding Access Log Entries to get a better sense of the logging experience on AWS.

Logging for HAProxy is complete.  Next, rsyslog and logrotate need to be configured.

Log Management

Storing the HAProxy logs, and rotating them is very important to this solution.  The script takes the rotated log, and stores it in the OSG bucket for the access logs.  The purpose of this is to make sure the file is not being written to when its being sent to the OSG bucket.  To start out, download the load-balancer.conf file to use with logrotate using curl:

# curl http://euca-elb-access-log-blog.s3.amazonaws.com/load-balancer.conf -o load-balancer.conf

This is the logrotate configuration file that the cronjob script will call to rotate the log file, then execute the access-log-transfer-s3.py script with a 1 day object lifecycle. To change the lifecycle, just change the value of the –lifecycle option in the load-balancer.conf file.

Next, update rsyslog to make sure the latest is running on the instance:

# yum upgrade rsyslog -y

After this has completed, add the following to the /etc/rsyslog.d/load-balancer.conf file:

local3.*       /var/log/load-balancer-access.log

Follow this step up by uncommenting and adding the following lines in /etc/rsyslog.conf:

$ModLoad imudp
$UDPServerAddress 127.0.0.1
$UDPServerRun 514

To wrap up, we need to add a script that will be kicked off by the cronjob.

Cronjob Script

To kick off the log rotation, add the ‘elb-logrotate‘ script to the instance using curl:

# curl http://euca-elb-access-log-blog.s3.amazonaws.com/elb-logrotate -o elb-logrotate

Using ‘crontab -e’, set up a cron for 5 minutes (or however often the access log information would like to be uploaded to the bucket):

*/5 * * * * /root/elb-logrotate

Clean Up

After completing all the customizations, the instance needs to be prepared for bundling.  Run the following commands to prepare the instance:

# echo "" > /etc/udev/rules.d/70-persistent-net.rules
# echo "" > /lib/udev/rules.d/75-persistent-net-generator.rules

If PERSISTENT_DHCLIENT is not in the  /etc/sysconfig/network-scripts/ifcfg-eth0 file, then add it:

# grep PERSISTENT_DHCLIENT /etc/sysconfig/network-scripts/ifcfg-eth0
# echo "PERSISTENT_DHCLIENT=yes" >> /etc/sysconfig/network-scripts/ifcfg-eth0

Now we can exit out the instance.

Creating the New Eucalyptus Load Balancer EMI

After finishing with the instance customizations, the instance is ready to be bundled and registered.  First, use euca-bundle-instance to bundle and upload the instance.  Use euca-describe-bundle-tasks to check on the status of the bundling operation.  Once the bundling operation has been completed, use euca-register to register the new ELB EMI:

# euca-bundle-instance -b load-balancer-access-logs -p eucalyptus-load-balancer-image-access-log i-315dd646
BUNDLE bun-315dd646 i-315dd646 load-balancer-access-logs eucalyptus-load-balancer-image-access-log 2014-12-11T04:07:59.835Z 2014-12-11T04:07:59.835Z pending 0 load-balancer-access-logs/eucalyptus-load-balancer-image-access-log.manifest.xml
....
# euca-describe-bundle-tasks
BUNDLE bun-315dd646 i-315dd646 load-balancer-access-logs eucalyptus-load-balancer-image-access-log 2014-12-11T04:07:59.835Z 2014-12-11T04:09:57.671Z complete 0 load-balancer-access-logs/eucalyptus-load-balancer-image-access-log.manifest.xml
# euca-register -a x86_64 -n load-balancer-access-logs load-balancer-access-logs/eucalyptus-load-balancer-image-access-log.manifest.xml --virtualization-type hvm
IMAGE emi-7a4367b8

Now that the new Eucalyptus Load Balancer EMI is register, update the cloud property ‘loadbalancing.loadbalancer_emi‘ to display the new ELB EMI:

# euca-modify-property -p loadbalancing.loadbalancer_emi=emi-7a4367b8
PROPERTY loadbalancing.loadbalancer_emi emi-7a4367b8 was emi-cf4fb988

Now, lets test out the changes.

Testing Out the ELB with Access Logging

To test it out, you can use either the Cloud Administrator, or a user from a ‘non-eucalyptus’ account.  In the example below, a user from a ‘non-eucalyptus’ account was used.  If a ‘non-eucalyptus’ account user is used, make sure the user has the appropriate IAM access policies for EC2 (Compute), S3 (OSG), and ELB (Eucalyptus Load Balancer).

First, create the Eucalyptus Load Balancer:

# eulb-create-lb hasp-euca-lb --listener "lb-port=80, protocol=http, instance-port=80, instance-protocol=http" --availability-zone Honest --region account2-user11@

Next, launch an instance that has a web service running on port 80.  In this example, I used a cloud-init configuration file to install nginx on an Ubuntu 14.04 (Trusty Tahr) Cloud Image:

# euca-run-instances -k account2-user11 -t m1.medium emi-59a742d0 --user-data-file nginx-cloudinit.config --region account2-user11@
....
# euca-describe-instances --region account2-user11@
RESERVATION r-5c16c716 325271821652 default
INSTANCE i-45c1ebd1 emi-59a742d0 euca-10-104-7-29.future.future.euca-hasp.cs.prc.eucalyptus-systems.com euca-172-17-248-189.future.internal running account2-user11 0 m1.medium 2014-12-05T21:53:51.197Z Honest monitoring-disabled 10.104.7.29 172.17.248.189 instance-store hvm sg-6ef9907f x86_64

Register the instance with the ELB:

# eulb-register-instances-with-lb --instances i-45c1ebd1 hasp-euca-lb --region account2-user11@
INSTANCE i-45c1ebd1

Generate some traffic to the ELB using curl or some other tool to populate the HAProxy log file.  Based upon how often the cronjob was set to execute, use s3cmd to see the bucket created in the ‘eucalyptus’ account (i.e. Cloud Administrator) for the access logs.  For information regarding s3cmd configuration files, refer to my previous blog:

# ./s3cmd/s3cmd --config=.s3cfg-cloud-admin ls

Once that has been confirmed, create another s3cmd configuration file for the ‘non-eucalyptus’ user, and confirm the user can list the contents of the bucket:

# ./s3cmd/s3cmd --config=.s3cfg-acct2-user11 ls s3://access_logs-hasp-euca-lb_10.104.7.9_315dd646

After that has been confirmed, download one of the log files and confirm the contents:

# ./s3cmd/s3cmd --config=.s3cfg-acct2-user11 get s3://access_logs-hasp-euca-lb_10.104.7.9_315dd646/elb-access-11122014-051353.log .

How is this ‘non-eucalyptus’ user able to see and download the contents of this bucket?  This is because of the script that creates the access log bucket, and uploads the logs to the bucket.  By grabbing the account ID from the instance metadata ‘security group’ category, the script adds bucket and object READ ACLs for the account ID.  The only issue here is that the cloud administrator will still need to communicate the bucket that the cloud user can access for the logs.  With the extra bonus of using the object lifecycle, the cloud administrator doesn’t have to worry about managing the buckets.  The objects will remove themselves after the define period of time.

Conclusion

Even though the solution isn’t exactly like AWS ELB Access Logs feature, it does provide a solution that is very similar to it.  The only thing missing is the service API interaction to enable/disable the access logging feature, set the interval and define the bucket that will be used.  Hopefully, this will be a feature we will see in the not too distant feature.  Thanks for hanging in there with me.  I hope you enjoy!  Feedback is always welcome.

Cheers!
