Re: Tomcat Cookbook and Oracle JDK


#1

Yep, you can, take a look at the examples in the readme -

Just override some attributes and it will install that version.

Also be sure to mirror the oracle binary locally in production, as
downloading directly can be troublesome at times

Well, this is weird.

Someone else replied before Eric and now that reply has disappeared. His
suggestion, well I was going to follow it, and it’s gone poof. Where did it
go?

I’m confused. The java cookbook in one place says if you want the oracle
java to include the ‘oracle’ recipe. Further down, it says to use
attributes. Which is it?

It’s also not clear now, and never has been, if setting
default[‘java’][‘install_flavor’] = ‘oracle’ in my wrapper cookbook will
have an effect on a cookbook two levels away in the stack. Ie if I have A
-> B -> C and cookbook A has default[‘java’][‘install_flavor’] =
‘oracle’… will that affect how cookbook B operates?

You probably want to do node.override[‘java’][‘install_flavor’] = 'oracle’
in your wrapper cookbook.

To answer on the 2 levels away: yes.

I’ll try to give an exemple:
Cookbook A depends on cookbook B wich in turns edpends on cookbook C.
Chef run will load attributes (which is a common hash for all cookbooks)
from C then B then A, so values in A will override thoose in C.

After that the recipe will be compiled.
For the Java cookbook it will do (from default.rb):

include_recipe “java::#{node[‘java’][‘install_flavor’]}”

So it will include the correct recipe from the attribute value.

Once the compilation is done, chef will enter the converge phase and act
on resources, setting them in the desired state (downloading jave, etc)

Hope it helps understanding how it works :wink:

Ah yes, the dreaded two phase compile thing that forces you to modify your
code to operate in a way that makes not much sense.

I’m already seeing this. My top level tomcat application cookbook set an
attribute:

node.override[‘slice-tomcat’][‘java_tier_options’] = " -Xms#{jvm_heap_min}M
-Xmx#{jvm_heap_max}M -Djava.awt.headless=true"

In it’s recipe, it then included the slice-tomcat (wrapper for tomcat)
recipe, and in it’s attributes file it has:

default[‘tomcat’][‘java_options’] = "${JAVA_OPTS}
-Dcom.sun.management.jmxremote"
default[‘tomcat’][‘java_options’] += "
-Dcom.sun.management.jmxremote.port=9010"
default[‘tomcat’][‘java_options’] += "
-Dcom.sun.management.jmxremote.rmi.port=9010"
default[‘tomcat’][‘java_options’] += "
-Dcom.sun.management.jmxremote.authenticate=false"
default[‘tomcat’][‘java_options’] += "
-Dcom.sun.management.jmxremote.ssl=false"
default[‘tomcat’][‘java_options’] +=
node[‘slice-tomcat’][‘java_tier_options’]

which fails because node[‘slice-tomcat’][‘java_tier_options’] isn’t set,
presumably because it’s operating only on attributes, and since
[‘slice-tomcat’][‘java_tier_options’] is set in a recipe, it hasn’t been
set yet.

Well, I might as well just do away with attributes files all together then.
Why bother? I’m now forced into putting attributes into recipes, which
probably isn’t the right way, but what is the alternative?

Doug.

Further to this, I could put the setting:

node.override[‘slice-tomcat’][‘java_tier_options’] =

in the top level cookbook’s attributes file. Presumably then, when it
includes the next one in the stack, the value would be set and all would be
ok. However, the value of this setting itself is calculated from the
instance type. This means I can’t put this in the attributes file. It has
to go in the recipe. Therefore, if it has to go in the recipe of the top
level cookbook, it also has to go in the recipe of the included cookbook.
Now we’re being forced to avoid usage of the attributes files and we have a
big mess.

Doug.

For thoose edge cases, you may use include_attributes to reload the
attribute file you know need it.

But as far as you tell it, just do a node[‘tomcat’][‘java_options’] += “
-Xms#{jvm_heap_min}M -Xmx#{jvm_heap_max}M -Djava.awt.headless=true” in
your recipe should do…

If you really have to use node.override (which I highly doubt a simple
node[‘attr’] should do) or wish to set in the recipe the value and then
reload the atrtibute file the idea would be to do something like:

in the attribute file:
[…sliced…]
default[‘tomcat’][‘java_options’] += "
-Dcom.sun.management.jmxremote.ssl=false"
default[‘tomcat’][‘java_options’] +=
node[‘slice-tomcat’][‘java_tier_options’] if
node.include?(‘slice-tomcat’) &&
node[‘slice-tomcat’].include?(‘java_tier_option’)

the if is evaluated left to right, if the first is false, it will stop
there and not raise a no method exception for [] on nil class on the
second one

then in your recipe

node[‘slice-tomcat’][‘java_tier_options’] += " -Xms#{jvm_heap_min}M
-Xmx#{jvm_heap_max}M -Djava.awt.headless=true"
include_attribute ‘slice-tomcat’

But generally if you have to set attributes in the recipe, you’re doing
something the wrong way somewhere.
You may have a better time namescoping by instance type,then you may
copy the correct namespaced attributes into the target one instead of
conditionnaly adding parameters. (you’ll still do something like
node[‘tomcat’][‘java_options’] = node[‘intance_type’][‘java-options’] at
the end, but it sounds less hard to maintain in time)

I’m perhaps not really clear, feel free to tell and I’ll try to write
something more structured :slight_smile:

include_recipe “java”

The java cookbook can install the Oracle JDK, but the defaut installs the OpenJDK. Is there a way I can override this without modifying the java or tomcat cookbooks?

Tensibai,

And now for my next trick, err issue.

I’m looking at our current server.xml in tomcat, which is created from a
whole bunch of grepping and sedding and the like. It manipulates things
that the tomcat cookbook has no control over. For example it disables the
APR stuff.

How on earth…? If I override the wrapped server.xml with rewrite in the
top level cookbook, then none of the variables that it expects are going
to be passed in, and it’s going to fail. :frowning:

Doug.

Further to this, I could put the setting:

node.override[‘slice-tomcat’][‘java_tier_options’] =

in the top level cookbook’s attributes file. Presumably then, when it
includes the next one in the stack, the value would be set and all would be
ok. However, the value of this setting itself is calculated from the
instance type. This means I can’t put this in the attributes file. It has
to go in the recipe. Therefore, if it has to go in the recipe of the top
level cookbook, it also has to go in the recipe of the included cookbook.
Now we’re being forced to avoid usage of the attributes files and we have a
big mess.

Doug.

For thoose edge cases, you may use include_attributes to reload the
attribute file you know need it.
But as far as you tell it, just do a node[‘tomcat’][‘java_options’] += “
-Xms#{jvm_heap_min}M -Xmx#{jvm_heap_max}M -Djava.awt.headless=true” in your
recipe should do…
If you really have to use node.override (which I highly doubt a simple
node[‘attr’] should do) or wish to set in the recipe the value and then
reload the atrtibute file the idea would be to do something like:
in the attribute file:
[…sliced…]
default[‘tomcat’][‘java_options’] += "
-Dcom.sun.management.jmxremote.ssl=false"
default[‘tomcat’][‘java_options’] +=
node[‘slice-tomcat’][‘java_tier_options’] if
node.include?(‘slice-tomcat’) &&
node[‘slice-tomcat’].include?(‘java_tier_option’)

the if is evaluated left to right, if the first is false, it will stop
there and not raise a no method exception for [] on nil class on the second
one

then in your recipe

node[‘slice-tomcat’][‘java_tier_options’] += " -Xms#{jvm_heap_min}M
-Xmx#{jvm_heap_max}M -Djava.awt.headless=true"
include_attribute ‘slice-tomcat’

But generally if you have to set attributes in the recipe, you’re doing
something the wrong way somewhere.
You may have a better time namescoping by instance type,then you may copy
the correct namespaced attributes into the target one instead of
conditionnaly adding parameters. (you’ll still do something like node[‘tomcat’][‘java_options’]
= node[‘intance_type’][‘java-options’] at the end, but it sounds less hard
to maintain in time)
I’m perhaps not really clear, feel free to tell and I’ll try to write
something more structured :slight_smile:

Ah yes, the dreaded two phase compile thing that forces you to modify
your code to operate in a way that makes not much sense.

I’m already seeing this. My top level tomcat application cookbook set an
attribute:

node.override[‘slice-tomcat’][‘java_tier_options’] = “
-Xms#{jvm_heap_min}M -Xmx#{jvm_heap_max}M -Djava.awt.headless=true”

In it’s recipe, it then included the slice-tomcat (wrapper for tomcat)
recipe, and in it’s attributes file it has:

default[‘tomcat’][‘java_options’] = "${JAVA_OPTS}
-Dcom.sun.management.jmxremote"
default[‘tomcat’][‘java_options’] += "
-Dcom.sun.management.jmxremote.port=9010"
default[‘tomcat’][‘java_options’] += "
-Dcom.sun.management.jmxremote.rmi.port=9010"
default[‘tomcat’][‘java_options’] += "
-Dcom.sun.management.jmxremote.authenticate=false"
default[‘tomcat’][‘java_options’] += "
-Dcom.sun.management.jmxremote.ssl=false"
default[‘tomcat’][‘java_options’] +=
node[‘slice-tomcat’][‘java_tier_options’]

which fails because node[‘slice-tomcat’][‘java_tier_options’] isn’t set,
presumably because it’s operating only on attributes, and since
[‘slice-tomcat’][‘java_tier_options’] is set in a recipe, it hasn’t been
set yet.

Well, I might as well just do away with attributes files all together
then. Why bother? I’m now forced into putting attributes into recipes,
which probably isn’t the right way, but what is the alternative?

Doug.

Well, this is weird.

Someone else replied before Eric and now that reply has disappeared. His
suggestion, well I was going to follow it, and it’s gone poof. Where did it
go?

I’m confused. The java cookbook in one place says if you want the oracle
java to include the ‘oracle’ recipe. Further down, it says to use
attributes. Which is it?

It’s also not clear now, and never has been, if setting
default[‘java’][‘install_flavor’] = ‘oracle’ in my wrapper cookbook will
have an effect on a cookbook two levels away in the stack. Ie if I have A
-> B -> C and cookbook A has default[‘java’][‘install_flavor’] =
‘oracle’… will that affect how cookbook B operates?

Doug.

To answer on the 2 levels away: yes.

I’ll try to give an exemple:
Cookbook A depends on cookbook B wich in turns edpends on cookbook C.
Chef run will load attributes (which is a common hash for all cookbooks) from C then B then A, so values in A will override thoose in C.

After that the recipe will be compiled.
For the Java cookbook it will do (from default.rb):

include_recipe "java::#{node['java']['install_flavor']}"

So it will include the correct recipe from the attribute value.

Once the compilation is done, chef will enter the converge phase and act on resources, setting them in the desired state (downloading jave, etc)

Hope it helps understanding how it works :wink:
