How to set up

• Use abst ctx fill {context} to fill your credentials for usage, you can find all the credentials on cloud provider site, leave context empty if you want to fill default
• Use abst ctx generate {context} to generate default config for context, leave context empty if you want to generate to default

Usage

Both commands do automatic reconnect on idle SSH Tunnel termination

• abst create forward/managed {context} for automatic Bastion session creation once deleted, will keep your, leave context empty if you want to use default connection alive till you kill this script
• abst do forward/managed {context} alias for abst create
• abst clean for removal all the saved credentials
• abst use {context} for using different config that you had filled, default is the default context in creds.json
• Use abst ctx locate {context} to locate your configs, leave context empty if you want to locate default

Context commands

• abst ctx list to list contexts
• abst ctx upgrade <context-name> to upgrade context you can use --all flag to upgrade all contexts
• abst ctx locate <context-name> to get a full path of context
• abst ctx share <context-name> to copy context contents into clipboard and display it, you can use --raw to just get json
• abst ctx paste <context-name> to paste contents into context file provided from name

Session commands

• abst ssh facilitates selecting an instance to connect to. The optional port argument can be specified partially; a connection is established if only one match is found. Use -n <context-name> to filter a connection, where the name can be a partial match. abst employs the in operator for searching and proceeds with SSH if a single matching instance exists.

Parallel execution

If you are more demanding and need to have connection to your SSH Tunnels ready at all times you can use parallel executed Bastions that currently work for full-auto forwarded setting

Change local port in the setting to port that is unique to other configs, and it will be running on all the added ports Until you kill the abst command, it will automatically remove all generated Bastion sessions by this program

• abst parallel add {context} will add context from your context folder to stack that will be executed
• abst parallel remove {context} will remove context from your context folder to stack that will be executed
• abst parallel run {context} will run all the stacked contexts
• abst parallel display will display current stacked contexts
• abst parallel list will list all sets with contexts

Helm registry commands

• abst helm login will log you in with credentials set in config.json, you set these credentials when running this command first time. Edit with flag --edit 1-n number is the index of credential in list
• abst helm push <chart-name> will push to specified remote branch, if more credentials preset it will let you pick which one to use

Kubectl commands

• abst pod ssh <part of name> will ssh into pod with similar name, if multiple found it will display select
• abst cp secret secret_namespace target_namespace source_namespace(optional) this will copy secret to target namespace, without providing source namespace it will use current as a source
