v0.1.1

This release fixes variable expansion clash whereby Crash Diagnostics would interpret variables early that are intended to be sent to remote servers. For instance, the following RUN would not work properly since $f would be interpreted by Crash Diagnostics as empty:

RUN /bin/bash -c 'for f in $(find /var/logs/containers -type f); do cat $f; done'

This PR introduces the ability to escape the variable expansion, allowing it to be sent to the server as intended as shown below:

RUN /bin/bash -c 'for f in \$(find /var/logs/containers -type f); do cat \$f; done'

See README for detail.

v0.1.0-alpha.9

This is a fix release that corrects the way directives such as RUN and CAPTURE handle embedded quotes (see issue #23 for detail). This release also adds the shell: named param to RUN and CAPTURE to specify a shell program to use to wrap a given command. So now the followings are supported for these two actions (note the way quotes can now be embedded):

• {RUN | CAPTURE} echo "Hello World!"
• {RUN | CAPTURE} "echo 'Hello World!'"
• {RUN | CAPTURE} 'echo "Hello World"'
• {RUN | CAPTURE} "/bin/sh -c 'date -u'"
• {RUN | CAPTURE} /bin/bash -c 'echo "Hello World"'
• {RUN | CAPTURE} cmd:"echo 'HELLO WORLD'"
• {RUN | CAPTURE} shell:"/bin/bash -c" cmd:"echo 'HELLO WORLD'"

v0.1.0-alpha.8

v0.1.0-alpha.8

This release introduces the new RUN directive to execute commands on remote machines without capturing the output in the generated archive file like CAPTURE. This is useful help interact with the remote nodes for tasks such as data preparation such as the following example:

# gather logs
RUN mkdir -p /tmp/all-logs
RUN cp /var/log/containers/* /tmp/all-logs 
RUN cp /var/log/kube-apiserver.log /tmp/all-logs
RUN cp /var/log/kubelet.log /tmp/all-logs
RUN cp /var/log/kube-proxy.log /tmp/all-logs

# copy all logs
COPY /tmp/all-logs

# clean up
RUN /usr/bin/rm -rf /tmp/all-logs

v0.1.0-alpha.7

v0.1.0-alpha.7

This release introduces Unix-style variable expansion in Diagnostics.file script. The previous Go-style templating has been deprecated in favor of the more traditional variable expansion.

Variable Expansion

Now all directives that appear in the Diagnostic script file can support variable expansion. This provides a more familiar feel to those with experience writing shell script. For instance, the following shows how variable expansion can be used in a Diagnostics script:

ENV clogs=/var/log/containers
ENV klogroot=/var/log
COPY ${clogs}
COPY $klogroot/kubelet.log
COPY ${klogroot}/kube-proxy.log
COPY ${klogroot}/kube-apiserver.log

Diagnostics script files can also access any environment variables made available to the process at runtime:

FROM 127.0.0.1:22
AUTHCONFIG username:${USER} private-key:${HOME}/.ssh/id_rsa
CAPTURE /bin/echo "HELLO WORLD"

v0.1.0-alpha.6

This release introduces better more robust directive string parsing with support for quoted values. With this release, the followings are possible:

• DIRECTIVE paramName:ParamValue example: WORKDIR path:/tmp/mypath
• DIRECTIVE paramName:"paramValue" example OUTPUT path:"/tmp/my dir"
• DIRECTIVE paramName:'value0 "value1"' example CAPTURE cmd:'/bin/echo "Hello World!"'

Also most directive also support now a default parameter than can be specified without a parameter name which can also support quoted values:

• WORKDIR "/tmp/my dir"
• ENV "key0=val0 key1=val1"
• Etc. (see documentation)

v0.1.0-alpha.5
