How to focus rake tests:

it 'does some sort of testing', :focus => true do

run_integration_specs(spec_path: 'spec/gocli/integration', tags: 'focus') or

rspec --tag focus spec/my_spec.rb

How to run bosh integration tests as a one-off in fly:

SPEC_PATH=spec/gocli/integration DB=postgresql CONCOURSE_TARGET=production be rake fly:integration

How to run BRATS as a one-off:

• When running older versions of concourse, using the -x flag, and referencing tmp directories as inputs, make sure to git init . && git add -N . to have it not be mad af.
• You probably want to run priviledged with -p
• Check the task yml and sh (specifically the exports) for all the fun answers.

Tmux:

• Ctrl + Space + S Sessions

Vim: Qutiting: ZZ :wq :x :cq - exit with an error code so git doesn't commit

Basic Movements:

• w start of next word
• b start of previous word
• e end of next word
• ge end of prev word

Inserting/Appending:

• Shift + a move to end of line and append
• Shift + i move to first char of line and insert

Line Movements:

• 0 start of current line
• ^ start of first word of current line
• $ end of current line

Buffer Movements:

• gg top of buffer
• G bottom of buffer
• <N>G or <N>gg move to line N

Moving Lines:

• Alt + J or Alt + K move the selected (or under cursor) line(s) up and down :D

• * will select the word/whatever under the cursor and find the next instance of it

• n next instance of that thing

Collapsing:

• z + c to collapse

• z + o to open

• z + a to collapse or open

• z + M collapse all levels (everything)

• z + R open all levels (everything)

• z + m collapse a level / increase fold level

• z + r open a level

Context-Aware splitting and joining

• g + S split the line onto multiple lines based on context
• g + J join the line onto a single line based on context

Ctrl + v to visually select Ctrl + n to add cursors on each line After visually selecting, use I to apply an insert to multiple lines Alt + m select everything under the cursor

Casing: c + r + _ or c + r + s changes case to snake case c + r + c changes case to camel case

daa delete around argument

ctags and navigating to function declarations:

• :!ctags -R to generate the ctags (while in nvim)
• Ctrl + ] go to declaration
• g + ] list declarations
• In go g + d will go to the definition (without the use of ctags)

Navigating quick fixes in vim unimpaired: [ + q last/prev/up an item in the list ] + q next/down an item in the list

Searching for stuff under the cursor:

• Space + s + g with no arguments
• Ctrl + r + Ctrl + w will paste whats under the cursor

Read in contents of file under cursor

• :r

Checking Resources

Checking resources on bosh-io-release resources: fly -t TEAM check-resource --resource=PIPELINE/RESOURCE --from=version:261.4

Checking Pivotal Network (Pivnet) resources: fly -t TEAM cr -r PIPELINE/RESOURCE -f product_version:2.4.6#2019-04-16T20:20:23.919Z One can get the correct product version via https://network.pivotal.io/api/v2/products/p-isolation-segment/releases/, combine version key with software_files_updated_at

Checking time resources: fly -t <your target> check-resource -r PIPELINE/RESOURCE --from "time:2000-01-01T00:00:00Z" # the important part

Easily script Tile build with timestamp names

export version="0.1.0-build.$(date '+%s')"; ./build.sh <( echo "${version}" ) .; om upload-product -p "pas-for-kubernetes-${version}.pivotal"

relengy (local version file)

export version="2.12.0-build.$(date '+%s')";echo "$version" > $PWD/version; STUB_RELEASES=true ./bin/build <( echo "${version}" ) .; smith om -- upload-product -p "srt-${version}.pivotal

investigate gq(q)

See the TCP ports current bound on (listening on) the system:

ss -ltnp

-l LISTENING
-t for TCP
-n NO hostname lookup
-p display the PROCESS using the socket

Run ginkgo tests (ONLY ONE):

--focus=REGEXP

If provided, Ginkgo will only run specs with descriptions that match the regular expression REGEXP.

Lifting the Service Account and CA from the current k8s config

CA

kubectl config view --raw --minify -o jsonpath='{.clusters[0].cluster.certificate-authority-data}' | base64 --decode

or
kubectl config view --minify -o json --raw | jq '.clusters[0].cluster["certificate-authority-data"]' -r | base64 --decode

Service Account Secret

kubectl config view --raw --minify -o jsonpath='{.users[0].user.token}'

Alt + N goes to the next instance of the errors.
